COST OF SOLICITATION OF PROXIES This Proxy solicitation is made by the Board of Directors of the Company, and the Company will bear the costs of this solicitation, including the expense of preparing, assembling, printing and mailing this Proxy Statement and any other material used in this solicitation of Proxies. This solicitation of Proxies will be made by mail and may be supplemented by telephone or other personal contact to be made without special compensation by regular officers and employees of the Company. If it should appear desirable to do so to ensure adequate representation at the Meeting, officers and regular employees may communicate with Stockholders, banks, brokerage houses, custodians, nominees and others, by telephone, facsimile transmissions, telegraph, or in person to request that Proxies be furnished. The Company will reimburse banks, brokerage houses, and other custodians, nominees and fiduciaries, for their reasonable expenses in forwarding proxy materials to their principals. The total estimated cost for the solicitation of Proxies is $9,000. OUTSTANDING SECURITIES AND VOTING RIGHTS; REVOCABILITY OF PROXIES The authorized capital of the Company consists of (i) 9,000,000 shares of common stock ("Common Stock"), $0.66-2/3 par value, of which 5,764,352 shares were issued and outstanding on the Record Date (with an additional 717,115 shares held as Treasury Stock) and (ii) 1,000,000 shares of Class A Preferred Stock, $1.00 par value ("Class A Preferred Stock"), of which no shares were issued and outstanding on the Record Date. The Common Stock and the Class A Preferred Stock are collectively referred to as the "Stock." A majority of the outstanding shares of the Common Stock constitutes a quorum for the conduct of business at the Meeting. Abstentions will be treated as shares present and entitled to vote for purposes of determining the presence of a quorum. 2

4 Each Stockholder is entitled to one vote, in person or by proxy, for each share of Common Stock standing in his or her name on the books of the Company as of the Record Date on any matter submitted to the Stockholders, except that in connection with the election of directors, each Stockholder has the right to cumulate votes, provided that the candidates' names have been properly placed in nomination prior to commencement of voting and a Stockholder has given notice prior to commencement of voting of his or her intention to cumulate votes. If a Stockholder has given such notice, all Stockholders may cumulate their votes for candidates in nomination. Cumulative voting entitles a Stockholder to give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of shares of Common Stock owned by such Stockholder, or to distribute such Stockholder's votes on the same principle among as many candidates as the Stockholder shall think fit. The candidates receiving the highest number of votes, up to the number of directors to be elected, shall be elected. Discretionary authority to cumulate is hereby solicited by the Board of Directors and the return of the Proxy shall grant such authority. Of the shares of Common Stock outstanding on the Record Date, 2,045,093 (or approximately 40.5%) (the "Shares") were held in the name of Lite-On Power Semiconductor Corporation ("LPSC"), which, in turn, is wholly-owned by Vishay/Lite-On Power Semiconductor, Pte., Ltd. ("Vishay/LPSC"), a joint venture between the Lite-On Group and Vishay Intertechnology, Inc. ("Vishay"). See "Security Ownership of Certain Beneficial Owners and Management" and "Certain Relationships and Related Transactions" for a discussion of the relationship among Vishay, Vishay/LPSC, LPSC and the Company. An additional 53,125 shares (or approximately 1.1%) were owned by directors and executive officers of the Company. Vishay/LPSC and each director and executive officer has informed the Company that it will vote "FOR" the election of the nominees to the Board of Directors identified herein and "FOR" the appointment of Moss Adams LLP as the Company's independent auditors. Each proposal described herein, other than the election of directors, requires the affirmative vote of a majority of the outstanding shares of Common Stock present in person or represented by proxy and entitled to vote at the Meeting. Accordingly, broker non-votes and abstentions from voting on any matter, other than the election of directors, will have the effect of a vote "AGAINST" such matter. A Proxy for use at the Meeting is enclosed. The Proxy must be signed and dated by you or your authorized representative or agent. Telegraphed, cabled or telecopied Proxies are also valid. You may revoke a Proxy at any time before it is exercised at the Meeting by submitting a written revocation to the Secretary of the Company or a duly executed Proxy bearing a later date or by voting in person at the Meeting. Brokers and nominees holding Common Stock in "street name" which are members of a stock exchange are required by the rules of the exchange to transmit this Proxy Statement to the beneficial owner of the Common Stock and to solicit voting instructions with respect to the matters submitted to the Stockholders. In the event any such broker or nominee has not received instructions from the beneficial owner by the date specified in the statement accompanying such material, the broker or nominee may give or authorize the giving of a Proxy to vote such Common Stock on the matters to be considered at the Meeting; provided, however, that the broker or nominee may not give or authorize the giving of a Proxy for any matter if it has notice of any contest with respect to any matter, and, provided further, that the broker or nominee may not vote the Common Stock "FOR" any matter which substantially affects the rights or privileges of the Common Stock without specific instructions from the beneficial owner. If you hold Common Stock in "street name" and you fail to instruct your broker or nominee as to how to vote such Common Stock, your broker or nominee may, in its discretion, vote such Common Stock "FOR" the election of the Board of Director's nominees and "FOR" the other proposals described herein. Unless revoked, the shares of Common Stock represented by Proxies will be voted in accordance with the instructions given thereon. In the absence of any instruction in the Proxy, your shares of Common Stock will be voted "FOR" the election of the nominees for director set forth herein and "FOR" the other proposals described herein. Recently, the Securities and Exchange Commission (the "SEC") amended its rule governing a company's ability to use discretionary proxy authority with respect to shareholder proposals with were not submitted by the shareholders in time to be included in the proxy statement. As a result of that rule change, in the event a shareholder proposal was not submitted to the Company prior to March 16, 1999, the enclosed Proxy will confer authority on the Proxyholder's to vote the shares in accordance with their best judgment and discretion if the proposal is presented at the Meeting. As of the date hereof, no shareholder proposal has been submitted to the Company, and management is not aware of any other matters to be presented for action at the Meeting. However, if any other matters properly come before the Meeting, the Proxies solicited hereby will be voted by the Proxyholder's in accordance with the recommendations of the Board of Directors. Such authorization includes authority to appoint a substitute nominee or 3

5 nominees to the Board of Directors' nominees identified herein where death, illness or other circumstances arise which prevent any such nominee for directors from serving in such position and to vote such Proxy for such substitute nominee.

10 Committee promotes communication between the management and the Board of Directors by receiving the periodic reports of the management of the Company on the business, results of operations, and prospects of the Company. The Board of Directors met one time during fiscal year 1998. The Compensation and Options Committee, the Audit Committee, and the Executive Committee each met once during fiscal year 1998. All of the persons who were directors of the Company or members of committees were present for all of the meetings during fiscal year 1998. EMPLOYEE BENEFITS PLANS The 1993 ISO Plan provides for the issuance of up to 1,000,000 shares of the Company's authorized but unissued Common Stock. Options granted under the 1993 ISO Plan are not transferable, except by will or the laws of descent or distribution. A vested but unexercised option is normally exercisable for 90 days after termination of employment, other than by death or retirement. In the event of death, unmatured options are accelerated to maturity. An option granted under the 1993 ISO Plan may not be priced at less than 100% of fair market value on the date of grant and expires 10 years from the date of grant. The 1993 NQO Plan became effective retroactively to July 6, 1993, upon approval by the shareholders at the Company's 1994 annual meeting. The 1993 NQO Plan provides for the issuance of up to 1,000,000 shares of the Company's authorized but unissued Common Stock. Options may be exercised by the optionee during his or her lifetime or after his or her death by those who have inherited by will or intestacy. A vested but unexercised option is normally exercisable for 90 days after termination of employment, other than by death or retirement. In the event of death, unmatured options are accelerated to maturity. The Compensation and Options Committee, which administers the 1993 NQO Plan, has full discretion to determine whether or not options granted under the 1993 NQO Plan shall have a right to relinquish up to one-half of an unexercised position of an option for an amount of cash, if concurrently, the holder of the option exercises a portion of the option and purchases a number of shares of stock at least equal to the number of shares which could have been purchased under the portion of the option relinquished ("SAR"). However, the Board of Directors has expressly stated that it has not and does not intend to grant such SAR. The shares to be issued upon exercise of options under the 1993 NQO Plan require a three-year vesting period. The option price is 100% of the fair market value of such shares on the date the option is granted. Options expire ten years from the grant of the option. The 1984 NQO Plan provides for the issuance of up to 300,000 shares of the Company's authorized but unissued Common Stock. Options granted under the 1984 NQO Plan are not transferable, except by will or the laws of descent or distribution. A vested but unexercised option is normally exercisable for 90 days after termination of employment, other than by death or retirement. In the event of death, unmatured options are accelerated to maturity. An option granted under the 1984 NQO Plan may not be priced at less than 100% of fair market value on the date of grant and expires 10 years from the date of grant. Under the terms of the 1984 NQO Plan, no options can be granted after 1994. The Company maintains a 401(k) profit sharing plan for the benefit of qualified employees. Employees who participate may elect to make salary deferral contributions to the Plan up to 6% of the employees' eligible payroll. The Company makes a contribution of $1 for every $2 contributed by the participant. In addition, the Company may make a discretionary contribution to the entire qualified employee pool, in accordance with the 401(k) Plan. COMPENSATION OF DIRECTORS All directors each received $750 for each meeting of the Board of Directors attended during the year ended December 31, 1998. No additional amounts are paid to directors for committee participation or special assignments. The Board of Directors may modify such compensation in the future. Both employee and non-employee directors are eligible to receive grants of stock options. COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934 Under Section 16(a) of the Exchange Act, the Company's directors, executive officers and any persons holding ten percent or more of the Common Stock are required to report their ownership of Common Stock and any changes in that ownership to the Securities and Exchange Commission (the "SEC") and to furnish the Company with copies of such reports. Specific due dates for these reports have been established and the Company is required to report 9

11 any failure to file on a timely basis by such persons. Based solely upon a review of copies of reports filed with the SEC during the fiscal year ended December 31, 1998, all reporting persons filed reports on a timely basis, except for Messrs. Schaedlich, Conahan, and Spires, who filed late Form 3's in connection with their election to the Company's Board of Directors in June 1998. To avoid the inadvertent failure of directors, executive officers and stockholders to timely file these reports in the future, the Company will periodically advise such persons of their filing obligations.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS TO STOCKHOLDERS The Report of the Compensation and Options Committee of the Board of Directors to Stockholders shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933 or under the Securities Exchange Act of 1934, except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under such Acts. REPORT OF THE COMPENSATION COMMITTEE The Compensation and Options Committee (the "Committee") consists of three directors, Dr. Shing Mao, William J. Spires, and Michael R. Giordano, who are not employees or former employees of the Company. The Compensation and Options Committee makes recommendations to the Board of Directors regarding compensation, benefits and incentive arrangements for officers and other key employees of the Company including awards under the Company's Incentive Bonus Plan. The Compensation and Options Committee also administers the Company's 1993 Incentive Stock Option Plan ("1993 ISO Plan"), the Company's 1993 Non-Qualified Stock Option Plan ("1993 NQO Plan"), and the Company's 1984 Non-Qualified Stock Option Plan ("1984 NQO Plan"). The Company's general approach to compensating executive officers is to pay cash salaries which are competitive with salaries paid to executives of other companies in the Company's industry, which are of similar size and engaged in a similar line of business, and to employ a subjective assessment of the individual's experience and past and potential contribution to the Company. The Company's policy in compensating executive officers is to establish methods and levels of compensation that will provide strong incentives to promote the profitability and growth of the Company and reward superior performance. Compensation of executive officers includes base salary, performance-based incentive bonuses and stock-based programs. Salaries are established by the Committee based on the Committee's subjective assessment of the executive's scope of responsibility, level of experience, individual performance, and contribution to the business. The Company believes that the emphasis on performance-based and stock-based compensation serves to align the interests of the executive officers with the interests of the Company's stockholders. The Company also seeks to establish overall compensation levels that are sufficiently competitive to attract, retain, and motivate highly 12

14 competent management personnel. Base salaries for Messrs. Wertz and Liu are paid in accordance with subjective criteria set by the Committee. The Company's performance, for purposes of compensation decisions, is measured under the annual bonus plan against goals established prior to the start of the fiscal year by the Committee, and is reviewed and approved by the Committee. The Company's annual bonus plan is based on specific financial performance results. Bonuses, set at a fixed amount and paid as a percentage of the total, are based upon reaching a percentage between 80% and 120% of the goal. Mr. Wertz's bonus is based upon subjective criteria set by the Committee. Mr. Liu's bonus is based on subjective criteria set by the Committee for net sales, and profit before tax at Diodes-Taiwan and Diodes-China, as well as, return on assets at Diodes-China. COMPENSATION FOR THE PRESIDENT AND CHIEF EXECUTIVE OFFICER No cash compensation, other than expense reimbursement, has been paid by the Company to Michael A. Rosenberg, the Company's President since his appointment in October 1997. Mr. Rosenberg serves as a consultant to Vishay Intertechnology, Inc., and he is compensated directly by Vishay for such consulting services. Mr. Rosenberg is however, eligible to participate in, and receive stock option grants through, the Company's 1993 Non-Qualified Stock Option Plan. Shares granted to Mr. Rosenberg previously were for his services as a member of the Company's Board of Directors. Any Shares that may be granted to Mr. Rosenberg in the future will be based upon the Committee's subjective assessment of the performance of Mr. Rosenberg and the Company. STOCK OPTIONS The Committee strongly believes that the interests of senior management must be closely aligned with those of the Company's stockholders. Stock options are granted to officers and selected employees whose contributions and skills are important to the long-term success of the Company. Stock options granted to executive officers to date have been granted at no less than the fair market value as of the date of grant with a ten year term. If employment is terminated, the term of the grant is 90 days from the termination date. To encourage retention, the ability to exercise options granted under the plans is subject to vesting restrictions. The Committee's policy is to award an initial grant at the date of employment, which vests over three years, and is in recognition of the executive officer's potential contribution to the Company. The three year vesting period may be increased or decreased at the Committee's discretion. After three years, it is at the Committee's discretion to award additional grants based upon future contribution. Decisions made by the Committee regarding the timing and size of other option grants take into consideration Company and individual performance, competitive market practices, and the size and term of option grants made in prior years. The Committee does not consider current option holdings when granting additional options. The Company's stock option plans have been amended and approved by the stockholders so stock options that have been awarded can qualify for exclusion under Section 162(m) of the Internal Revenue Code of 1986 as performance-based compensation. Dated: April 2, 1999 Compensation and Options Committee of the Board of Directors Michael R. Giordano Shing Mao William J. Spires COMPENSATION AND OPTIONS COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Compensation and Options Committee consists of three directors, Dr. Shing Mao, William J. Spires, and Michael R. Giordano. No person who served as a member of the Company's Compensation and Options Committee during the 1998 fiscal year has ever been an officer or employee of the Company or any of its subsidiaries. 13

The peer group companies consist of Microsemi Corporation, Nu-Horizons Electronics Corporation, Siliconix, Inc., Semtech Corporation, Sterling Electronics Corporation, Unitrode Corporation, Savior Technology Group (which acquired former peer group company Western Microtechnology, Inc. in 1997), and Taitron Components, Inc. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS LPSC is the record owner of 40.5% of the Company's issued and outstanding Common Stock, excluding treasury stock, at December 31, 1998, and the Record Date. In August 1997, the ownership of LPSC was transferred to Vishay/LPSC, a newly formed joint venture between the Lite-On Group and Vishay. Vishay holds a 65% interest in the joint venture, and the Lite-On Group holds the other 35%. 14

16 During the years ended December 31, 1998 and 1997, approximately 25% and 32%, respectively, of the purchases of products for resale by the Company, amounting to approximately $12,320,000 and $15,630,000, respectively, were from Vishay/LPSC. These products, which were also available generally from other sources, were negotiated at prices competitive with prices charged by other vendors of similar products in similar quantities. There are no special or exclusive trading agreements or understandings between the Company and LPSC, other than the Company's previously filed marketing agreement with LPSC. In February 1996, the Company announced an agreement with FabTech whereby the Company may purchase processed wafers used in the manufacture of several types of discrete semiconductors. The Company has provided FabTech with approximately $2.5 million in working capital to be used in upgrading, reconfiguring, and starting up operations at an existing wafer fabrication facility located in Lee's Summit, Missouri. The Company earns interest from FabTech on the $2.5 million advance at a rate equal to the Company's current cost of capital. FabTech is a wholly-owned subsidiary of Vishay/LPSC. The Company's Taiwan and China manufacturing facilities receive wafers from FabTech, among others. Output from the FabTech facility includes wafers used in the production of Schottky barrier diodes, fast recovery epitaxial diodes (FREDs), and other widely used value-added products. Schottky barrier diodes are employed in the manufacture of the power supplies found in personal computers, telecommunications devices and other applications where high frequency, low forward voltage and fast recovery are required. Raymond Soong, who became a director and Chairman of the Board of the Company effective March 16, 1993, is also the Chairman of the Board of Silitek, Vishay/LPSC, Taiwan Liton, and the Diodes-China joint venture. Michael A. Rosenberg, President, Chief Executive Officer and a director of the Company, also serves as a consultant to Vishay, for which consulting services he is compensated by Vishay. David Lin, who has been a director of the Company since 1991, was from March 1993 to October 1997, President and Chief Executive Officer of the Company. Mr. Lin is the President and a director of Silitek. Mr. Lin is also a director of the Diodes-China joint venture. Silitek is affiliated through common ownership and control with Taiwan Liton, and both companies are members of the Lite-On Group. Both Silitek and Taiwan Liton are public corporations in Taiwan with stock registered on the Taipei Stock Exchange. Dr. Shing Mao, who is a director of the Company, is Chairman of the Board of Lite-On Milpitas, a wholly-owned subsidiary of Taiwan Liton. Dr. Mao is also a director of Vishay/LPSC, and since 1995, has also been a director of FabTech. M.K. Lu, who has been a director of the Company since 1995, is also Group Vice President of the Lite-On Group. From 1983 to 1990, Mr. Lu was General Manager/Vice President of Silitek. Mr. Lu is also a director of the Diodes-China joint venture. During 1998, Michael R. Giordano, a director of the Company and Senior Vice President-Investment Consulting at the investment banking firm of PaineWebber, Inc., has, from time to time, assisted directors and executive officers of the Company in stock option exercises and subsequent stock sales of the Company's Common Stock. Mr. Giordano is also the pension consultant for the Company's 401(k) plan and has, from time to time, in such capacity assisted Vishay/LPSC in stock transactions. Compensation received by Mr. Giordano for services rendered to the Company and Vishay/LPSC for services other than as a director in 1998 was less than $1,000. Joseph Liu, Vice President, Far East Operations, is also President of Vishay/LPSC and President and a director of the Diodes-China joint venture. THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE ELECTION OF THE BOARD OF DIRECTORS' NOMINEES. 15

17 PROPOSAL TWO - RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS The firm of Moss Adams LLP, certified accountants, has been the Company's independent accountants since 1993 and has been selected by the Board of Directors to serve as its independent accountants for the fiscal year ending December 31, 1999. Professional services rendered by Moss Adams LLP for the fiscal year ended December 31, 1998 consisted of an audit of the Company's financial statements, consultation on interim financial statements, services related to filings with the SEC, meetings with the Company's Audit Committee and consultation on various matters relating to accounting and financial reporting. All professional services rendered by Moss Adams LLP during fiscal 1998 were furnished at customary rates and terms. The Audit Committee of the Board of Directors met with representatives of Moss Adams LLP during the past fiscal year. The members of the Audit Committee are Messrs. Giordano, Mao, and Silverman. Representatives of Moss Adams LLP are expected to be present at the Meeting. They will have the opportunity to make a statement, if they so desire, and respond to appropriate questions from stockholders. Stockholders are being asked to ratify the appointment of Moss Adams LLP as the Company's independent public accountants for the fiscal year ending December 31, 1999. Ratification of the proposal requires the affirmative vote of a majority of the shares of Common Stock represented and voting at the Meeting. THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS. PROPOSALS OF STOCKHOLDERS Under certain circumstances, stockholders are entitled to present proposals at stockholder meetings. Any such proposal to be included in the proxy statement for the Company's 2000 annual meeting of stockholders must be submitted by a stockholder prior to December 31, 1999, in a form that complies with applicable regulations. Recently, the SEC amended its rule governing a company's ability to use discretionary proxy authority with respect to shareholder proposals which are not submitted by the shareholders in time to be included in the proxy statement. As a result of that rule change, in the event a shareholder proposal is not submitted to the Company prior to March 15, 2000, the proxies solicited by the Board of Directors for the 2000 annual meeting of shareholders will confer authority of the holders of the proxy to vote the shares in accordance with their best judgment and discretion if the proposal is presented at the 2000 annual meeting of shareholders without any discussion of the proposal in the proxy statement for such meeting. ANNUAL REPORT AND FORM 10-K The Company's Annual Report of the fiscal year ended December 31, 1998 accompanies or has preceded this Proxy Statement.
