N-Channel Enhancement Mode Field Effect Transistor
General Description
These N-Channel enhancement mode power field effect
transistors are produced using Fairchild's proprietary,
high cell density, DMOS technology. This very high
density process has been especially tailored to minimize
on-state resistance, provide superior switching
performance, and withstand high energy pulses in the
avalanche and commutation modes. These devices are
particularly suited for low voltage applications such as
automotive, DC/DC converters, PWM motor controls, and
other battery powered circuits where fast switching, low
in-line power loss, and resistance to transients are
needed.
