BUS21B NPN Transistor

The BUS21B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUS21B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUS21B transistor symbol shows an arrow from the base into the emitter. This means that the current flows from collector terminal to emitter terminal.

Circuit diagram symbol of the BUS21B transistor as follows.
