MMUN2211LT1 Series
Preferred Device


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
COLLECTOR
resistor. The BRT eliminates these individual components by
(OUTPUT)
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 SOT-23 R1
package which is designed for low power surface mount applications. PIN 1 R2
