Overview
The MUN5211T1 is a dual NPN silicon bias resistor transistor produced by onsemi. This device is designed to integrate 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 MUN5211T1 is particularly useful in applications where space and component count are critical factors.
