Vishay Launches 240-Milliohm, 200-V Switching MOSFET in 3.3-mm by 3.3-mm PowerPAK® 1212-8

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

SANTA CLARA, CALIFORNIA — April 7, 2004 — 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 (V_GS=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.
