Overview
The SMMUN2216LT1G is a digital transistor produced by onsemi, part of their series of Bias Resistor Transistors (BRT). This device integrates a single transistor with a monolithic bias resistor 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 SMMUN2216LT1G is packaged in a SOT-23 (TO-236) lead-free package, making it suitable for various applications requiring compact and efficient solutions.
