Overview
The SMUN5111T1G is a PNP Bipolar Digital Transistor (BRT) produced by onsemi. This device is part of the MUN5111T1 series, designed to replace a single transistor and its external resistor bias network with a single integrated device. The Bias Resistor Transistor (BRT) includes 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 SMUN5111T1G is AEC-Q101 qualified and PPAP capable, making it suitable for automotive and other applications requiring unique site and control change requirements. The device is also PbFree, Halogen Free/BFR Free, and RoHS compliant.
