DTC114EET1 SERIES 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 http://onsemi.com 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 NPN SILICON integrating them into a single device. The use of a BRT can reduce BIAS RESISTOR both system cost and board space. The device is housed in the TRANSISTORS SC–75/SOT–416 package which is designed for low power surface mount applications. • Simplifies Circuit Design 3 • Reduces Board Space
