N-Channel Enhancement Mode Field Effect Transistor
General Description
Power SOT 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 DC motor control
and DC/DC conversion where fast switching, low in-line power
loss, and resistance to transients are needed.
