Such documents need not be filed with the Commission either as part of this Registration Statement or as prospectuses or prospectus supplements pursuant to Securities Act Rule 424 in accordance with the Note to Part I of Form S-8. These documents, and the documents incorporated by reference in this Registration Statement pursuant to Item 3 of Form S-8, taken together, constitute a prospectus that meets the requirements of Section 10(a) of the Securities Act. PART II INFORMATION REQUIRED IN THE REGISTRATION STATEMENT Item 3. Incorporation of Documents by Reference. The following documents previously filed by the Company with the Commission are incorporated herein by reference: (a) The Company's Annual Report on Form 10-K for its fiscal year ended December 31, 2002, filed with the Commission on March 31, 2003; (b) The Company's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2003, filed with the Commission on May 14, 2003; (c) All other reports filed pursuant to Sections 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, since the end of the fiscal year covered by the annual report referred to in (a) above; and (d) The description of the Company's Common Stock contained in the Company's Registration Statement on Form 8-A (File No. 00030811), filed with the Commission on June 15, 2000, including any amendment or report filed for the purposes of updating such description.

Any such statement so modified or superseded shall not be deemed, except as so modified or amended, to constitute a part of this Registration Statement. Item 4. Description of Securities. Not applicable. 2

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. 3

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 4

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. Item 7. Exemption from Registration Claimed. Not applicable. Item 8. Exhibits. Exhibit Number Description of Exhibit ------ ---------------------- 3.1 Certificate of Incorporation of Diodes Incorporated, as amended to date 3.2 Bylaws of Diodes Incorporated (1) 5.1 Opinion of Sheppard, Mullin, Richter & Hampton LLP 23.1 Consent of Moss Adams LLP 23.2 Consent of Sheppard, Mullin, Richter & Hampton LLP (included in its opinion filed as Exhibit 5.1) 24.1 Power of Attorney (See page 7) - --------------------- (1) 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 5

(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. 6

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

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.

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

them, as he sees fit.

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.

                  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 1,000,000 shares of the Company's Common Stock 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  therefor received) pursuant to the provisions of the Plan and the
stock option agreements  provided for under the Plan, and in accordance with the
Registration  Statement,  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.

                  This opinion  letter is rendered as of the date first  written
above and we  disclaim  any  obligation  to advise you of facts,  circumstances,
events or developments which hereafter may be brought to our attention and which
may  alter,  affect or modify  the  opinion  expressed  herein.  Our  opinion is
expressly  limited  to the  matters  set forth  above and we render no  opinion,
whether by  implication  or otherwise,  as to any other matters  relating to the
Company,  the Plan, or the shares of the Company's  common stock  issuable under
the Plan.

                             Respectfully submitted,

                              /S/

                              SHEPPARD, MULLIN, RICHTER & HAMPTON LLP

                          INDEPENDENT AUDITORS' CONSENT

         We  hereby   consent  to  the   incorporation   by  reference  in  this
Registration  Statement  on Form  S-8 of our  report  dated  January  27,  2003,
appearing in the Annual Report on Form 10-K of Diodes  Incorporated for the year
ended December 31, 2002.
