P-Channel Enhancement Mode Field Effect Transistor
General Description Features
Power SOT 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 and provide superior
switching performance. These devices are particularly
suited for low voltage applications such as notebook
computer power management, battery powered circuits,
and DC motor control.
