Overview
The MMUN2211LT1 is a Bias Resistor Transistor (BRT) from onsemi, designed to replace a single device and its external resistor bias network. This NPN bipolar digital transistor integrates a monolithic bias network consisting of two resistors: a series base resistor and a base-emitter resistor. This integration simplifies circuit design, reduces board space, and decreases the overall component count. The MMUN2211LT1 is AEC-Q101 qualified and PPAP capable, making it suitable for automotive and other applications requiring unique site and control change requirements. Additionally, these devices are PbFree, Halogen Free/BFR Free, and RoHS compliant.
