NDS9400A
Single P-Channel Enhancement Mode Field Effect Transistor
General Description
These P-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 notebook computer power management and other battery
powered circuits where fast switching, low in-line power loss,
and resistance to transients are needed.
