Bias Resistor Transistor
NPN Silicon Surface Mount Transistor
with Monolithic Bias Resistor Network
This new series of digital transistors is designed to replace a single
device and its external resistor bias network. The BRT (Bias Resistor
Transistor) contains a single transistor with a monolithic bias network con-
sisting of two resistors; a series base resistor and a base–emitter resistor.
The BRT eliminates these individual components by integrating them into a
single device. The use of a BRT can reduce both system cost and board
space. The device is housed in the SC–70/SOT–323 package which is
designed for low power surface mount applications.
