OFFER ON-RESISTANCE DOWN TO 1.2 Ω IN SC-70 AND SOT-23 PACKAGES
30 April 2006 - Vishay Electronic

A family of new,150-V and 200 V p channel power MOSFETs that offers space-saving solutions for active clamp configurations were released today by Siliconix incorporated an 80.4%-owned subsidiary of Vishay Intertechnology, Inc.

While p-channel MOSFETs for active clamps offer a simpler alternative to n-channel clamp implementations, until now the majority of devices suitable for this application were available only in larger packages such as the SO-8 and DPAK. With the new devices in the SOT-23 and SC-70, Siliconix brings together small size and on-resistance values at least 80% better than the nearest competing devices.

Built on Siliconix's advanced p channel TrenchFET technology, the compact dimensions of these new p channel power MOSFETs reduce board space requirements to enable smaller overall product design without sacrificing performance. Because p channel drive circuitry is less complicated than that of n-channel solutions, these new devices also allow designers to implement smaller, lower-cost active clamp designs in small and intermediate-sized power converters.

The power MOSFETs released today are intended for primary-side active clamp circuits in dc-to-dc converters for telecom, datacom, and industrial products. With on-resistance values ranging from 1.2 ohms to 2.35 ohms, these power MOSFETs represent industry-best on-resistance for their respective footprints.
