SEMICONDUCTOR TECHNICAL DATA DTC 101 ~ 108 DTC 110 ~ 112 / 114 /117 DTC 123 / 124 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 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. 3 2 1 SOT–23 (TO–236AB) • Simplifies Circuit Design • Reduces Board Space and Component Count • The SOT-23 package can be soldered using wave or reflow. The modified gull-winged leads absorb thermal stress during soldering eliminating the possibility of damage to the die. PIN 3 PIN 1 BASE (INPUT) R1 COLLECTOR (OUTPUT) PIN 2 [ … ]
