LESHAN RADIO COMPANY, LTD.Bias Resistor TransistorsLMUN2110LT1GPNP Silicon Surface Mount TransistorsSerieswith Monolithic Bias Resistor Network3This new series of digital transistors is designed to replace a singledevice and its external resistor bias network. The BRT (Bias Resistor1Transistor) contains a single transistor with a monolithic bias network2consisting of two resistors; a series base resistor and a base-emitterresistor. The BRT eliminates these individual components bySOT-23integrating them into a single device. The use of a BRT can reduceboth system cost and board space. The device is housed in the SOT-23PIN 3package which is designed for low power surface mount applications.R1 COLLECTORPIN 1(OUTPUT) Simplifies Circuit DesignBASE(INPUT)R2 Reduces Board SpacePIN 2EMITTER Reduces Component Count(GROUND)
