Description

UniFET

MOSFET is Fairchild Semiconductor’s high voltage

MOSFET family based on planar stripe and DMOS technology.

This MOSFET is tailored to reduce on-state resistance, and to

provide better switching performance and higher avalanche

energy strength. This device family is suitable for switching

power converter applications such as power factor correction

(PFC), flat panel display (FPD) TV power, ATX and electronic

lamp ballasts.
