Preferred Devices
Dual Common Emitter Bias
Resistor Transistors
PNP Silicon Surface Mount Transistors
with Monolithic Bias Resistor 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. These digital transistors are
designed to replace a single device and its external resistor bias
network. The BRT eliminates these individual components by
integrating them into a single device. In the UMC2NT1 series, two
BRT devices are housed in the SOT−353 package which is ideal for
low power surface mount applications where board space is at a
premium.
