LESHAN RADIO COMPANY, LTD.
Bias Resistor Transistor
PNP Silicon Surface Mount Transistor
with Monolithic Bias Resistor Network
This new digital transistor is designed to replace a single device
and its external resistor bias network. The BRT (Bias Resistor Tra-
nsistor) 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–89 package which is designed for low power surface mount
applications.
