Overview
The MUN5211DW1T1G is a Dual NPN Bias Resistor Transistor (BRT) produced by onsemi. This device integrates a single transistor with a monolithic bias network consisting of two resistors, a series base resistor (R1) and a base-emitter resistor (R2), each with a value of 10 kΩ. This integration simplifies circuit design, reduces board space, and minimizes the component count. The MUN5211DW1T1G is packaged in a SOT-363 (6-TSSOP) surface mount package and is RoHS compliant, Pb-free, and halogen-free/BFR-free, making it suitable for various applications, including automotive and other environments requiring unique site and control change requirements.
