Overview
The SMUN5214DW1T1G is a dual NPN bias resistor transistor produced by onsemi. This device is part of a series designed to replace a single transistor and its external resistor bias network with a single integrated component. The Bias Resistor Transistor (BRT) contains a monolithic bias network consisting of two resistors, simplifying circuit design and reducing both system cost and board space. It 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 Pb-free, halogen-free, and RoHS compliant.
