This N-Channel enhancement mode power MOSFET is pro
duced 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 en
ergy strength. These devices are suitable for switched mode
power supplies, audio amplifier, DC motor control, and variable
switching power applications.
