BS170 / MMBF170
N-Channel Enhancement Mode Field Effect Transistor
BS170 / MMBF170 — N-Channel Enhancement Mode Field Effect Transistor
General Description
These N-Channel enhancement mode field ef fec t
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.
Features
■ High density cell design for low R
■ Voltage controlled small signal switch.
■ Rugged and reliable.
■ High saturation current capability.
These products are particularly sui ted for low vol tage, low
current applications such as small servo motor control,
power MOSFET gate drivers, and other switching
applications.
