MMUN2111LT1G Series

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 http://onsemi.com
Transistor) contains a single transistor with a monolithic bias network
consisting of two resistors; a series base resistor and a base-emitter PIN 3
resistor. The BRT eliminates these individual components by COLLECTOR
PIN 1 R1 (OUTPUT)
integrating them into a single device. The use of a BRT can reduce BASE
both system cost and board space. The device is housed in the SOT-23 (INPUT) R2
package which is designed for low power surface mount applications. PIN 2
