BC122 NPN Transistor

The BC122 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BC122 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC122 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 BC122 transistor as follows.
