FQA70N15

N-Channel QFET

MOSFET

150 V, 70 A, 28 mΩ

Description

This N-Channel enhancement mode power MOSFET

is produced using Fairchild Semiconductor’s

proprietary planar stripe a

nd DMOS technology. This

advanced MOSFET technology has been especially

tailored to reduce on-state resistance, and to provide

superior switching performance and high avalanche

energy strength. These devices are suitable for switched

mode power supplies, audio amplifier, DC motor control,

and variable switching power applications.
