BC321B PNP Transistor

The BC321B is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BC321B transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC321B 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 BC321B transistor as follows.
