Bias Resistor Transistors

PNP 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 SOT-723 package

which is designed for low power surface mount applications.
