P-Channel Logic Level Enhancement Mode Field Effect Transistor
General Description
SuperSOT
TM
-3 P-Channel logic level 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. These devices are particularly suited for low voltage
applications such as notebook computer power management,
portable electronics, and other battery powered circuits where
fast high-side switching, and low in-line power loss are needed
in a very small outline surface mount package.
