BSS84 / BSS110
P-Channel Enhancement Mode Field Effect Transistor
General Description Features
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 designed to minimize on-state resistance, provide
rugged and reliable performance and fast switching. They
can be used, with a minimum of effort, in most applications
requiring up to 0.17A DC and can deliver pulsed currents up
to 0.68A. This product is particularly suited to low voltage
applications requiring a low current high side switch.
