Dual Bias Resistor Transistors
PNP Silicon Surface Mount Transistors with
Monolithic Bias Resistor Network
Motorola Preferred Devices
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 MUN5111DW1T1 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.
