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 is
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.
