MOTOROLA Order this document SEMICONDUCTOR TECHNICAL DATA by MUN5211DW1T1/D MUN5211DW1T1 Dual Bias Resistor Transistors SERIES NPN 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 6 5 device and its external resistor bias network. The BRT eliminates these 4 individual components by integrating them into a single device. In the 1 MUN5211DW1T1 series, two BRT devices are housed in the SOT–363 2 3 package which is ideal for low power surface mount applications where board CASE 419B–01, STYL
