ST12 NPN Transistor

The ST12 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the ST12 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The ST12 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 ST12 transistor as follows.
