Dual Bias ResistorTransistors
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鈥揺mitter 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鈥?63 package which
is ideal for low power surface mount applications where board space is at a premium.
