MUN5311DW1T1 Series
Preferred Devices
Dual Bias Resistor
Transistors
NPN and 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 MUN5311DW1T1 series,
two complementary BRT devices are housed in the SOT−363 package
which is ideal for low power surface mount applications where board
space is at a premium.
