NEW SUR FAMILY OF TRENCHFET POWER MOSFETS FEATURES REVERSE-LEAD TO-252 PACKAGE
25 February 2004 - Vishay Electronic

Siliconix incorporated, an 80.4%-owned subsidiary of Vishay Intertechnology, Inc., today announced a new family of TrenchFET power MOSFETs in a reverse-lead TO-252 DPAK package.

The reverse-formed leads of the "SUR"-packaged TrenchFETs allow the device to be mounted inversely on the PCB with a heat sink on top, enabling cooler operation. Because heat generated from power can be dissipated to the air rather than to the PCB, each of these power MOSFETs features a lower effective on-resistance value and higher current capability than DPAK power MOSFETs with conventional lead-outs. Cooler operation also takes thermal stress off the board, contributing to better overall reliability.

Used for desktop computer core dc-to-dc conversion applications, the SUR power MOSFETs enable the design of "greener" VRM modules and PC motherboards that use power more efficiently and require fewer components.

The 20-V SUR70N02-04P and 30 V SUR50N03-06P, SUR50N03-09P, SUR50N03-12P, and SUR50N03-16P power MOSFETs offer a range of on-resistance values from 4 mΩ to 16 mΩ and can serve as both synchronous and control FETs in dc-to-dc converters.
