Overview
The SMMUN2214LT1G is an NPN bipolar digital transistor (BRT) produced by onsemi. This device is designed to simplify circuit design by integrating a single transistor with a monolithic bias resistor network, consisting of two resistors: a series base resistor and a base-emitter resistor. This integration reduces both system cost and board space. The SMMUN2214LT1G is AEC-Q101 qualified and PPAP capable, making it suitable for automotive and other applications requiring unique site and control change requirements. It is also Pb-free, halogen-free/BFR-free, and RoHS compliant.
