Dual N-Channel Enhancement Mode Field Effect Transistor
General Description
SO-8 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 and provide superior switching
performance. These devices are particularly suited for
low voltage applications such as notebook computer
power management and other battery powered circuits
where fast switching, low in-line power loss, and
resistance to transients are needed.
