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 high energy pulse in the
avalanche and commutation modes. These devices are
well suited for low voltage applications such as audio
amplifiers, high efficiency switching DC/DC converters, and
DC motor control.
