BC340 NPN Transistor

The BC340 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BC340 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC340 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 BC340 transistor as follows.
