N-Channel Enhancement Mode Field Effect Transistor
General Description Features
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.
