General Description

These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary,
planar stripe, DMOS technology.
This advanced technology is especially tailored to minimize
on-state resistance, provide superior switching
performance, and withstand a high energy pulse in the
avalanche and commutation modes. These devices are
well suited for low voltage applications such as automotive,
high efficiency switching for DC/DC converters, and DC
motor control.
