BC857AR PNP Transistor

The BC857AR is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BC857AR transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC857AR transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.

Circuit diagram symbol of the BC857AR transistor as follows.
