Bias Resistor Transistor
NPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network
This new series of digital transistors is designed to replace a single device and its external resistor bias 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. 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. The device is housed in the SOT-23 package which is designed for low power surface mount applications.
