Overview
The MMUN2211LT1G is a digital transistor from onsemi, part of their series of Bias Resistor Transistors (BRT). This device is designed to integrate a single transistor with a monolithic bias resistor network, consisting of a series base resistor and a base-emitter resistor. This integration simplifies circuit design, reduces board space, and decreases the overall component count. The MMUN2211LT1G is particularly useful in applications requiring compact and efficient transistor solutions.
