Fairchild Semiconductor HUFA75321D3, HUFA75321D3S Datasheet

HUFA75321D3, HUFA75321D3S

Data Sheet December 2001

20A, 55V, 0.036 Ohm, N-Channel UltraFE T
Power MOSFETs

These N-Channel pow er MOSFETs
are manufactured using the
innovat ive Ul traFET® pr ocess . This

advanced process technology
achieves the lowest possible on-resistance per silicon area,
resulting in outsta nding performance. This device is capable
of withstanding hi gh energy in the ava lan che mode and the
diode exhibits very low reverse recovery time and stored
charge. It was designed for use in applications where power
efficiency is important, such as switching regulators,
switching converters, motor drivers, relay drivers, low­voltage bus switches, and pow er management in portable
and battery-operated products.

Formerly developmental type TA75321.
