Bias Resistor Transistor MMUN2111LT1
PNP Silicon Surface Mount Transistor with
Monolithic Bias Resistor Network SERIES
Motorola Preferred Devices
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 PNP SILICON
by integrating them into a single device. The use of a BRT can reduce both system BIAS RESISTOR
cost and board space. The device is housed in the SOT-23 package which is TRANSISTOR
designed for low power surface mount applications.
