Dual Bias Resistor Transistors 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−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 MUN5211DW1T1 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. Features • Simplifies Circuit Design • Reduces Board Space • Reduces Component Count • Pb−Free Packages are Available
