Si7820DN�s Small Size and High Power Capability Are Essential to Implementation of New Sub-Brick DC/DC Power Architectures

In a critical advance that will help designers meet the stringent power-density and packaging requirements of new sub-brick power architectures, Siliconix incorporated (NASDAQ: SILI), an 80.4%-owned subsidiary of Vishay Intertechnology, Inc. (NYSE: VSH), today announced the industry�s first 200 V power MOSFET available in the compact PowerPAK� 1212-8 package.

Intended for primary dc-to-dc switching applications for power supplies in fixed telecom networks and routers, the new n channel Si7820DN TrenchFET� power MOSFET is the smallest 200-V device on the market suited for power switching.

The PowerPAK 1212-8 package measures 3.3 mm by 3.3 mm with a low 1.07 mm height profile, offering smaller dimensions than SO-8 solutions while providing greatly superior thermal performance. Power dissipation for the PowerPAK 1212-8 package is 3.8 W, nearly double that of any MOSFET device with a TSSOP-8-size footprint or smaller. Typical thermal resistance is just 1.9 C/W compared to 16 C/W for the SO-8.

In addition to space savings and its high voltage capability, the Si7820DN features on-resistance of 240 mΩ and a typical gate charge of 12.1 nC (VGS=10 V). The new power MOSFET is rated for an operating junction and storage temperature range of �55 C to +150 C.

Samples of the 200 V Si7820DN TrenchFET power MOSFET are available now, with lead times of 10 to 12 weeks for production quantities. Pricing for U.S. delivery in 10,000-piece quantities is $1.26.

Siliconix is a leading manufacturer of power MOSFETs, power ICs, analog switches, and multiplexers for computers, cell phones, fixed communications networks, automobiles, and other consumer and industrial electronic systems. With 2002 worldwide sales of $372.9 million, the Company's facilities include a Class 1 wafer fab dedicated to the manufacture of power products in Santa Clara, California, and an affiliated Class 1 wafer fab located in Itzehoe, Germany. The Company�s products are also fabricated by subcontractors in Japan, Germany, China, and Taiwan. Assembly and test facilities include a company-owned facility in Taiwan, a joint venture in Shanghai, China, and subcontractors in the Philippines, China, Taiwan, Israel, and the United States.

Vishay, a Fortune 1,000 Company listed on the NYSE, is one of the world's largest manufacturers of discrete semiconductors (diodes, rectifiers, transistors, optoelectronics, and selected ICs) and passive electronic components (resistors, capacitors, inductors, and transducers). The Company�s components can be found in products manufactured in a very broad range of industries worldwide. Vishay is headquartered in Malvern, Pennsylvania, and has plants in 17 countries employing over 25,000 people. Vishay can be found on the Internet at http://www.vishay.com.
