Preferred Devices

Bias Resistor Transistors

NPN Silicon Surface Mount Transistors

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

consisting 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-59 package which is designed for low power surface

mount applications.
