Dual Bias Resistor Transistors
SC-88/SOT-363 Package
MUN52xxDW1T1
Series
NPN 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 MUN5211DW1T1 series, two 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.
