The MMUN2233LT1G is a NPN Transistor with monolithic bias resistor network. The Bias Resistor Transistor (BRT) contains a single transistor with a monolithic bias network consisting of two resistors, a series base resistor and a base emitter resistor. The BRT eliminates these individual components by integrating them into a single device. The use of a BRT can reduce both system cost and board space.
