MMUN2211LT1G Series

Bias Resistor Transistor
NPN Silicon Surface Mount Transistor
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
integrating them into a single device. The use of a BRT can reduce R1 (OUTPUT)
both system cost and board space. The device is housed in the
PIN 1 R2
SOT-23 package which is designed for low power surface mount
BASE PIN 2
applications. (INPUT) EMITTER
