Digital Transistors (BRT)

R1 = 47 kW, R2 = 22 kW

PNP Transistors with Monolithic Bias

Resistor Network

This series of digital transistors is designed to replace a single

device and its external resistor bias network. The Bias Resistor

Transistor (BRT) 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.
