1 EXHIBIT 99.1 Michael Rosenberg, President Philip Bourdillon Diodes Incorporated Silverman Heller Associates (805) 446-4800 (310) 208-2550 DIODES COMMENTS ON VISHAY/LPSC ANNOUNCEMENT Westlake Village, California -- March 28, 2000 -- Diodes Incorporated (Amex: DIO), a manufacturer of discrete semiconductors, today commented on yesterday's announcement by Vishay Intertechnology, Inc. (NYSE: VSH) that it has agreed to sell its 65% interest in Lite-On Power Semiconductor Corporation ("LPSC") to Lite-On JV Corporation ("Lite-On Group") in a transaction that is expected to close before September 30, 2000. LPSC has been Diodes' largest shareholder since 1991 and is member of the Lite-On Group, a leading manufacturer of power semiconductors, computer peripherals, and communication products. In July 1997, Vishay and the Lite-On Group, a Taiwanese consortium, formed a joint venture ("Vishay/LPSC") to acquire LPSC. Diodes' long-standing relationship with LPSC, which currently holds approximately 38% of the Company's Common Stock, is anticipated to be unaffected by the transaction, said Michael Rosenberg, President and CEO of Diodes Incorporated. "Although we have enjoyed the relationship with Vishay and believe it to have been mutually beneficial," said Rosenberg, "we are looking forward to continued support from the manufacturing base of the Lite-On Group." "Our customers continue to recognize Diodes' brand products and view the Company as a separate vendor from Vishay," Mr. Rosenberg continued, "and management believes that with the Company's competitive pricing, internal manufacturing capabilities and capacity, customer/applications engineering, and strong customer service reputation, it has proven itself to be a valuable supplier. Accordingly, the Vishay/LPSC transaction is not anticipated to have a materially adverse impact on customer relations." Pursuant to the Vishay/Lite-On transaction, three members of the Company's Board of Directors Eugene R. Conahan, Erich E. Schaedlich, and William J. Spires, each an employee of Vishay have resigned effective March 27, 2000. Mr. Rosenberg added that first-quarter 2000 financial results are expected to substantially exceed fourth-quarter 1999 results, which were the strongest in the Company's history. Diodes Incorporated (Amex: DIO) manufactures high-quality discrete semiconductor devices and provides customer support to leading manufacturers in the automotive, electronics, computing and telecommunications industries. Through the Company's ISO-9000 and QS-9000 certified manufacturing facilities located in Shanghai, China and Taipei, Taiwan, Diodes' products include small signal transistors and MOSFETs, transient voltage suppressors (TVSs), zeners, Schottkys, diodes, rectifiers and bridges.
