MOSFET
80 V, 90 A, 16 mΩ
Description
This N-Channel enhancement mode power MOSFET
is produced
using Fairchild Semiconductor’s
proprietary planar stripe and 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.
