ITEM 4.           DESCRIPTION OF SECURITIES.

                  Not applicable.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

                  Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

                  Section 145 of the Delaware  General  Corporation Law provides
that a  corporation  may  indemnify  directors  and  officers  as well as  other
employees  and  individuals  against  expenses   (including   attorneys'  fees),
judgments,  fines and amounts paid in settlement in  connection  with  specified
actions,  suits or  proceedings,  whether  civil,  criminal,  administrative  or
investigative  (other than an action by or in the right of the  corporation or a
derivative  action), if they acted in good faith and in a manner they reasonably
believed to be in or not opposed to the best interests of the  corporation  and,
with respect to any criminal action or proceedings,  had no reasonable  cause to
believe their conduct was unlawful.

                  A similar standard applies in the case of derivative  actions,
except that indemnification only extends to expenses (including attorneys' fees)
actually and reasonably incurred in connection with the defense or settlement of
such action,  and the statute  requires court  approval  before there can be any
indemnification  where the person seeking  indemnification has been found liable
to the  corporation.  The statute  provides  that it is not  exclusive  of other
indemnification   that  may  be  granted  by  a  corporation's   certificate  of
incorporation,  bylaws, disinterested director vote, stockholder vote, agreement
or otherwise.

                  As  permitted   by  Section  145  of  the   Delaware   General
Corporation Law, Article EIGHTH of the Company's  Certificate of  Incorporation,
as amended, provides:

                  "The Company  shall  indemnify any and all persons whom it has
                  the power to indemnify pursuant to the General Corporation Law
                  of Delaware  against any and all expenses,  judgments,  fines,
                  amounts paid in settlement,  and any other  liabilities to the
                  fullest  extent   permitted  by  such  Law  and  may,  at  the
                  discretion  of the Board of  Directors,  purchase and maintain
                  insurance,  at its expense, to protect itself and such persons
                  against  any such  expense,  judgment,  fine,  amount  paid in
                  settlement  or other  liability,  whether  or not the  Company
                  would have the power to so  indemnify  such  person  under the
                  General Corporation Law of Delaware."

                  Also as  permitted  by  Section  145 of the  Delaware  General
Corporation Law, Article IV of the Company's Bylaws, as amended, provides:

                  "Section 1. This  corporation  shall  indemnify any person who
                  was or is a party or is  threatened  to be made a party to any
                  threatened,  pending or completed action,  suit or proceeding,
                  whether,  civil,  criminal,  administrative  or  investigative
                  (other than an action by or in the right of this  corporation)
                  by reason of the fact that he is or was a  director,  officer,
                  employee or agent of this corporation, or is or was serving at
                  the  request  of  this  corporation  as a  director,  officer,
                  employee or agent of another corporation,  partnership,  joint
                  venture,   trust  or  other   enterprise,   against   expenses
                  (including attorney's fees), judgments, fines and amounts paid
                  in  settlement  actually  and  reasonably  incurred  by him in
                  connection with such action, suit or proceeding if he acted in
                  good faith and in a manner he reasonably  believed to be in or
                  not opposed to the best  interests of this  corporation,  and,
                  with  respect to any  criminal  action or  proceeding,  had no
                  reasonable  cause to believe  his conduct  was  unlawful.  The
                  termination  of any action,  suit or  proceeding  by judgment,
                  order,   settlement,   conviction  or  upon  a  plea  of  nolo
                  contendere or its equivalent,  shall not, of itself,  create a
                  presumption that the person did not act in good faith and in a
                  manner which he reasonably believed to be in or not opposed to
                  the best  interests of this  corporation,  and with respect to
                  any criminal  action or proceeding,  had  reasonable  cause to
                  believe that his conduct was unlawful.

                  Section 2. This corporation shall indemnify any person who was
                  or is a party,  or is  threatened  to be made a party,  to any
                  threatened,  pending or completed  action or suit by or in the
                  right of this  corporation  to procure a judgment in its favor
                  by reason of the fact that he is or was a  director,  officer,
                  employee or agent of this corporation, or is or was serving at
                  the  request  of  the  corporation  as  a  director,  officer,
                  employee or agent of another corporation,  partnership,  joint
                  venture, trust or other enterprise against expenses (including
                  attorneys'  fees) actually and  reasonably  incurred by him in
                  connection  with the defense or  settlement  of such action or
                  suit if he acted in good  faith and in a manner he  reasonably
                  believed to be in, or not opposed  to, the best  interests  of
                  this corporation,  and except that no indemnification shall be
                  made in respect of any claim, issue or matter as to which such
                  person shall have been adjudged to be liable for negligence or
                  misconduct in the performance of his duty to this  corporation
                  unless and only to the extent  that the Court of  Chancery  or
                  the  court in which  such  action  or suit was  brought  shall
                  determine upon application  that,  despite the adjudication of
                  liability  but in view of all the  circumstances  of the case,
                  such expenses  which the Court of Chancery or such other court
                  shall deem proper.

                  Section 3. To the extent that a director, officer, employee or
                  agent of a  corporation  has been  successful on the merits or
                  otherwise  in  defense  of  any  action,  suit  or  proceeding
                  referred  to in  Sections 1 and 2, or in defense of any claim,
                  issue or  matter  therein,  he shall  be  indemnified  against
                  expenses  (including  attorney's fees) actually and reasonably
                  incurred by him in connection therewith.

                  Section 4. Any  indemnification  under Section 1 and 2 (unless
                  ordered by a court) shall be made by this  corporation only as
                  authorized  in the  specific  case upon a  determination  that
                  indemnification of the director, officer, employee or agent is
                  proper in the circumstances  because he has met the applicable
                  standard  of  conduct  set  forth in  Sections  1 and 2.  Such
                  determination shall be made (1) by the Board of Directors by a
                  majority vote of a quorum consisting of directors who were not
                  parties to such action,  suit or proceeding,  or (2) if such a
                  quorum is not obtainable,  or, even if obtainable, a quorum of
                  disinterested  directors  so  directs,  by  independent  legal
                  counsel in a written opinion, or (3) by the stockholders.

                  Section 5. Expenses  incurred in defending a civil or criminal
                  action,  suit or proceeding may be paid by this corporation in
                  advance  of the  final  disposition  of such  action,  suit or
                  proceeding  as  authorized  by the Board of  Directors  in the
                  specific case upon receipt of an  undertaking  by or on behalf
                  of the  director,  officer,  employee  or agent to repay  such
                  amount unless it shall  ultimately  be  determined  that he is
                  entitled to be indemnified  by this  corporation as authorized
                  by this by-law.

                  Section 6. The  indemnification  provided in this by-law shall
                  not be deemed  exclusive  of any other  rights to which  those
                  seeking  indemnification  may be  entitled  under any  by-law,
                  agreement,  vote of stockholders or disinterested directors or
                  otherwise,  both as to action in his official  capacity and as
                  to action in another  capacity while holding such office,  and
                  shall continue as to a person who has ceased to be a director,
                  officer,  employee  or agent and shall inure to the benefit of
                  the heirs, executors and administrators of such a person.

                  Section 7. This  corporation,  when authorized by the Board of
                  Directors,  shall purchase and maintain insurance on behalf of
                  any  person who is or was a  director,  officer,  employee  or
                  agent of this corporation, or is or was serving at the request
                  of this corporation as a director,  officer, employee or agent
                  of another corporation,  partnership,  joint venture, trust or
                  other  enterprise  against any liability  asserted against him
                  and  incurred by him in any such  capacity,  or arising out of
                  his status as such, whether or not this corporation would have
                  the power to indemnify  him against such  liability  under the
                  provisions of this by-law."

                  The Company  maintains an insurance  policy  pursuant to which
the directors and certain officers of the Company are insured, within the limits
and  subject to the  limitations  of the  policy,  against  certain  expenses in
connection  with the defense of certain claims,  actions,  suits or proceedings,
and  certain  liabilities  which  might be imposed  as a result of such  claims,
actions,  suits or  proceedings,  which may be brought against them by reason of
their being or having been such directors or officers.

(1)      Incorporated by reference to Exhibit 3.1 to the Company's  Registration
         Statement on Form S-8 (File No. 333-106775),  filed with the Securities
         and Exchange Commission on July 2, 2003.




(2)      Incorporated by reference to Exhibit 3.2 to the Company's  Registration
         Statement on Form 8-A (File No.  00030811),  filed with the  Securities
         and Exchange Commission on June 15, 2000.


ITEM 9.           UNDERTAKINGS.

(a)               The undersigned registrant hereby undertakes:

(1)      To file,  during  any  period in which  offers or sales  are being
                   made,  a  post-effective  amendment  to this  Registration
                   Statement:

(i)               To include any prospectus  required by Section 10(a)(3) of the
                  Securities Act;

(ii)     To reflect  in the  prospectus  any facts or events  arising
               after the effective date of this  Registration  Statement (or the
               most recent post-effective amendment thereof) which, individually
               or in  the  aggregate,  represent  a  fundamental  change  in the
               information   set   forth   in   this   Registration   Statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of  securities  offered (if the total dollar value of  securities
               offered  would not  exceed  that  which was  registered)  and any
               deviation  from  the low or  high  end of the  estimated  maximum
               offering  range may be reflected in the form of prospectus  filed
               with the Commission pursuant to Rule 424(b) if, in the aggregate,
               the  changes  in  volume  and price  represent  no more than a 20
               percent change in the maximum aggregate  offering price set forth
               in the  "Calculation of Registration  Fee" table in the effective
               registration statement; and

(iii)             To include any material  information  with respect to the plan
                  of distribution not previously  disclosed in this Registration
                  Statement or any material  change to such  information in this
                  Registration Statement;

                  PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do
                  not apply if the  registration  statement is on Form S-3, Form
                  S-8 or Form S-3, and the  information  required to be included
                  in a post-effective amendment by those paragraphs is contained
                  in periodic  reports filed with or furnished to the Commission
                  by the  registrant  pursuant  to  Section  13 or  15(d) of the
                  Exchange  Act  that  are  incorporated  by  reference  in this
                  Registration Statement.

(2)      That, for the purpose of determining any liability under the Securities
         Act,  each such  post-effective  amendment  shall be deemed to be a new
         registration  statement relating to the securities offered therein, and
         the offering of such  securities at that time shall be deemed to be the
         initial BONA FIDE offering thereof.

(3)      To remove from registration by means of a post-effective  amendment any
         of  the  securities   being  registered  which  remain  unsold  at  the
         termination of the offering.

(b)      The  undersigned  registrant  hereby  undertakes  that, for purposes of
         determining  any liability under the Securities Act, each filing of the
         registrant's  annual  report  pursuant to Section 13(a) or 15(d) of the
         Exchange Act (and, where applicable, each filing of an employee benefit
         plan's  annual  report  pursuant to Section  15(d) of the Exchange Act)
         that is incorporated by reference in this Registration  Statement shall
         be deemed to be a new registration statement relating to the securities
         offered therein, and the offering of such securities at that time shall
         be deemed to be the initial bona fide offering thereof.

 (c)           Insofar as indemnification  for liabilities arising under the
               Securities Act may be permitted to directors,  executive officers
               and  controlling  persons  of  the  registrant  pursuant  to  the
               foregoing  provisions,  or  otherwise,  the  registrant  has been
               advised   that   in   the   opinion   of  the   Commission   such
               indemnification  is against  public  policy as  expressed  in the
               Securities  Act and is,  therefore,  unenforceable.  In the event
               that a claim for indemnification  against such liabilities (other
               than the payment by the  registrant of expenses  incurred or paid
               by a director, officer or controlling person of the registrant in
               the  successful  defense of any action,  suit or  proceeding)  is
               asserted  by such  director,  officer  or  controlling  person in
               connection with the securities being  registered,  the registrant
               will,  unless in the  opinion of its  counsel the matter has been
               settled  by   controlling   precedent,   submit  to  a  court  of
               appropriate    jurisdiction    the    question    whether    such
               indemnification  by it is against  public  policy as expressed in
               the Securities Act and will be governed by the final adjudication
               of such issue.



                                   SIGNATURES

         Pursuant to the  requirements  of the  Securities  Act, the  registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-8 and has  duly  caused  this  Registration
Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized,  in the City of Westlake  Village,  State of  California,  on May 9,
2005.

statement, including any post-effective amendments, or appendices or supplements
that  may be  required  to be  filed  under  the Act to keep  such  registration
statement effective or to terminate its effectiveness.

                  Further,  the undersigned do hereby  authorize and direct such

executed or filed by the undersigned respectively.

                  This Power of Attorney  shall  remain in full force and effect
until revoked or superseded by written notice filed with the SEC.

                                       OF
                               DIODES INCORPORATED


Filed with the  Secretary of State of the State of Delaware on July 29, 1968. As
amended on June 14, 2000.

         FIRST:   The name of the corporation (hereinafter called the "Company")
                  is DIODES INCORPORATED.

         SECOND:  The registered  office of the Company in the State of Delaware
is located at 100 West Tenth Street, in the City of Wilmington, in the County of
New Castle.  The name of its registered agent at that address is The Corporation
Trust Company.

         THIRD:   The nature of the business, or objects or purposes to be
                  transacted, promoted, or carried on are as follows:

         (1)  To  engage  in the  business  of  manufacturing  solid  state  and
electronic devices.

         (2) To do everything necessary,  proper,  advisable,  or convenient for
the  accomplishment  of the purposes  hereinabove set forth, and to do all other
things  incidental  thereto  connected  therewith,  which are not  forbidden  by
statute or by this Certificate of Incorporation.

         (3) To engage in any lawful act or activity for which  corporations may
be organized under the General Corporation Law of Delaware.

         (4) To carry  out the  purposes  hereinabove  set  forth in any  state,
territory,  district  or  possession  of the United  States,  or in any  foreign
country,  to the extent that such  purposes are not forbidden by the law of such
state, territory, district or possession of the United States or by such foreign
country;  and, in the case of any state or territory,  district or possession of
the United States, or any foreign country, in which one or more of such purposes
are  forbidden  by law, to limit the  purpose or purposes  for which the company
proposes to carry on in such state,  territory,  district or  possession  of the
United  States,  or foreign  country,  to such  purpose or  purposes  as are not
forbidden by the law thereof, and any certificate for application to do business
in such  state,  territory,  district or  possession  of the United  States,  or
foreign country.

         FOURTH:  The  Company  is  authorized  to issue a total  of  thirty-one
million  (31,000,000)  shares of all classes of stock.  Of such total  number of
authorized shares of stock, thirty million (30,000,000) shares are Common Stock,
each of which shares of Common Stock has a par value of Sixty-Six and Two-Thirds
Cents ($.66-2/3),  and one million  (1,000,000) shares are Preferred Stock, each
of which shares of Preferred Stock has a par value of One Dollar ($1.00).

         A statement of the  designations of the authorized  classes of stock or
of any series thereof, and the powers, preferences and relative,  participating,
optional  or  other  special   rights,   and   qualifications,   limitations  or
restrictions  thereof,  or of the  authority of the Board of Directors to fix by
resolution or resolutions such designations and other terms, is as follows:

         (1)      Preferred Stock:
         Shares of  Preferred  Stock  may be issued  from time to time in one or
more series.

         The Board of Directors is hereby authorized, within the limitations and
restrictions  stated in this Article FOURTH, to fix by resolution or resolutions
the  designation of each series of Preferred  Stock and the powers,  preferences
and   relative,   participating,   optional  or  other   special   rights,   and
qualifications, limitations or restrictions thereof, including, without limiting
the generality of the foregoing,  such  provisions as may be desired  concerning
voting,  redemption,  dividends,  dissolution  or the  distribution  of  assets,
conversion  or exchange,  and such other  subjects or matters as may be fixed by
resolution  or  resolutions  of  the  Board  of  Directors   under  the  General
Corporation Law of Delaware.

         If any proposed  amendment to the Certificate of  Incorporation  of the
Company would alter or change the preferences, special rights or powers given to
any one or more  outstanding  series of  Preferred  Stock,  so as to affect such
series adversely, or would authorize the issuance of a class or classes of stock
having  preferences  or rights with respect to dividends or  dissolution  or the
distribution  of assets that would be superior to the  preferences  or rights of
such  series  of  Preferred  Stock , then the  holders  of each  such  series of
Preferred  Stock so  affected  by the  amendment  shall be entitled to vote as a
series upon such amendment,  and the affirmative vote of two-thirds (2/3) of the
outstanding  shares of each  such  series  shall be  necessary  to the  adoption
thereof,  in  addition  to such other  vote as may be  required  by the  General
Corporation Law of Delaware.

         The number of authorized  shares of Preferred Stock may be increased or
decreased by the  affirmative  vote of the holders of a majority of the stock of
the Company entitled to vote,  without there being a class vote of the Preferred
Stock.

         (2) Common Stock:

         Subject to all of the  preferences and rights of the Preferred Stock or
a series  thereof that may be fixed by a resolution or resolutions of the Boards
of Directors,  dividends may be paid on the Common Stock as and when declared by
the Board of Directors,  out of any funds of the Company  legally  available for
the payment of such dividends.

         Except as may otherwise be provided by a resolution or  resolutions  of
the Board of Directors concerning the Preferred Stock or a series thereof, or by
this Certificate of  Incorporation  or the General  Corporation Law of Delaware,
the holders of the shares of Common Stock issued and outstanding  shall have and
possess  the  exclusive  right  to  notice  of  stockholders'  meetings  and the
exclusive power to vote.

       FIFTH:   The name and mailing address of the incorporation is as follows:

            NAME                                   ADDRESS

         A.D.  Grier                         100  West  Tenth  Street
                                             Wilmington, Delaware

SIXTH:  At all elections of Directors of the Company,  each  stockholder  who is
entitled to vote upon such election  shall be entitled to as many votes as shall
be  equal to the  number  of  votes  which  (except  for  this  provision  as to
cumulative voting)
 he would be entitled to cast for the election of Directors  with respect to his
shares of stock multiplied by the number of Directors to be elected,  and he may
cast all of such votes for a single  Director or may  distribute  them among the
number to be voted for or for any two or more of them, as he sees fit.

         SEVENTH:  In furtherance and not in limitation of the powers  conferred
by statute,  the Board of Directors is expressly  authorized  to make,  alter or
repeal the By-Laws of the Company.

         EIGHTH: The Company shall indemnify any and all persons whom it has the
power to indemnify  pursuant to the General  Corporation Law of Delaware against
any and all expenses,  judgments,  fines,  amounts paid in  settlement,  and any
other  liabilities to the fullest  extent  permitted by such Law and may, at the
discretion of the Board of Directors,  purchase and maintain  insurance,  at its
expense, to protect itself and such persons against any such expense,  judgment,
fine,  amount paid in settlement or other liability,  whether or not the Company
would have the power to so indemnify  such person under the General  Corporation
Law of Delaware.

Diodes Incorporated
3050 East Hillcrest Drive
Westlake Village, California  91362

                  Re:      REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

                  We have acted as special  counsel  to Diodes  Incorporated,  a
Delaware  corporation  (the  "Company"),  in connection with the registration on
Form S-8 (the  "Registration  Statement")  under the  Securities Act of 1933, as
amended,  of 1,500,000 shares of the Company's Common Stock, $0.66 2/3 par value
per share,  reserved for issuance under the 2001 Omnibus  Equity  Incentive Plan
(the "Plan") of the Company.  This opinion is being furnished in accordance with
the requirements of Item 8 of Form S-8 and Item 601(b)(5)(i) of Regulation S-K.

                  We have  reviewed  the  Company's  charter  documents  and the
corporate  proceedings taken by the Company with respect to the establishment of
the  Plan.  With  respect  to the  foregoing  documents,  we  have  assumed  the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals and the conformity to originals of all documents submitted to us as
certified or reproduced  copies.  We also have obtained from the officers of the
Company  certificates as to certain factual matters necessary for the purpose of
this opinion and,  insofar as this opinion is based on matters of fact,  we have
relied on such certificates without independent investigation.

                  Based on such review,  we are of the opinion that,  if, as and
when the  shares of the  Company's  Common  Stock are  issued  and sold (and the
consideration  therefore received and appropriate stock  certificates  therefore
executed and delivered) pursuant to the provisions of the Plan, such shares will
be legally issued, fully paid and nonassessable.

                  We consent to the filing of this opinion letter as Exhibit 5.1
to the Registration Statement.

                  We express no opinion as to matters governed by any laws other
than the Delaware  General  Corporation  Law, the  applicable  provisions of the
Delaware Constitution and reported decisions of the Delaware courts interpreting
these laws.

                  We  express no opinion on  securities  issue  pursuant  to any
