WESTLAKE VILLAGE, Calif.--(BUSINESS WIRE)--Dec. 17, 2004--

                Previous Licensing Agreement Expands to
                   Diodes, Inc.'S New Product Family

Diodes Incorporated (NASDAQ:DIOD) today announced it has signed an agreement with Microsemi Corporation (NASDAQ:MSCC) allowing Microsemi to license Diodes' newly released, patent-pending PowerDI(TM)5 package.

Diodes Incorporated, headquartered in Westlake Village, California, is a leading manufacturer and supplier of high-quality discrete semiconductor products, and Microsemi Corporation, headquartered in Irvine, California, is a market-leading designer, manufacturer and marketer of analog, mixed-signal and discrete semiconductors.

"We are very excited about this reciprocal licensing agreement with Microsemi," said C.H. Chen, President and CEO of Diodes, Inc. "Our collaboration in the past has been mutually beneficial as the unique strength of Microsemi's proprietary technology in our products has allowed us to build on our existing range of industry-leading diode, rectifier and protection devices while Microsemi has gained broadened industry acceptance of its advanced proprietary technology through having Diodes, Inc. as a second source. We are therefore looking forward to continuing this productive collaboration for our new proprietary Power DI(TM)5 series."

"This reciprocal agreement will allow us to leverage Diodes' innovative packaging technology to further exploit the numerous commercial applications that exist among our customer base and served markets," said James J. Peterson, President and CEO of Microsemi. "Customers and end-users are the ones who benefit most from this reciprocal agreement through the companies' increased ability to continue to develop and offer state-of-the-art products with leading edge technology."

About PowerDI(TM)5

Diodes' new patent-pending PowerDI(TM)5 accommodates larger die sizes and higher amperage than other high-performance packages currently available. As a result, this broadens the range of high-performance next-generation discrete devices that Diodes is now able to offer its customers. The release of this new proprietary patent-pending package is building upon the momentum generated by the performance packaging platforms of Diodes, Inc's' PowerDI(TM)123 proprietary technology as well as Microsemi's proprietary technology. The first products in the recently released PowerDI(TM)5 family were the high-efficiency 3 Ampere, 200 Volt low leakage Schottky Barrier rectifier device PDS3200, and the 5 Ampere, 100 volt low leakage PDS5100H.

Diodes, Inc.'s compact proprietary packaging designs offers significant advantages over larger and higher profile D-PAK technology, providing exceptionally low thermal resistance and high power density, which are key benefits in power management and DC to DC conversion applications. In addition, the low profile of these devises that are roughly a third of the size of comparable devices, offers a practical alternative to available chip scale packaging techniques used in high-density packaging designs.

    PowerDI is a trademark of Diodes Incorporated.
