Product Description
Product Overview
The BRT (Bias Resistor Transistor) is a series of NPN silicon surface mount transistors featuring a monolithic bias resistor network. Designed to replace a single transistor and its external bias resistors, the BRT integrates a base resistor (R1) and a base-emitter resistor (R2) into a single device. This integration simplifies circuit design, reduces board space, and lowers component count, making it ideal for low-power surface mount applications. The SC-89 package is suitable for wave or reflow soldering, with modified gull-winged leads designed to absorb thermal stress and prevent die damage. These devices are RoHS compliant and available in various configurations with different resistor values. The S- prefix indicates suitability for automotive and other applications requiring unique site and control change requirements, with AEC-Q101 qualification and PPAP capability.
