BC349B NPN Transistor

The BC349B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BC349B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC349B 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 BC349B transistor as follows.
