BS170 / MMBF170 — N-Channel Enhancement Mode Field Effect Transistor
March 2010
BS170 / MMBF170
N-Channel Enhancement Mode Field Effect Transistor
General Description
These N-Channel enhancement mode field effect
transistors are produced using Fairchild's proprietary, high
cell density, DMOS technology. These products have been
designed to minimize on-state resistance while provide
rugged, reliable, and fast switching performance. They can
be used in most applications requiring up to 500mA DC.
These products are particularly suited for low voltage, low
current applications such as small servo motor control,
power MOSFET gate drivers, and other switching
applications.
Features
