BC557AP PNP Transistor

The BC557AP is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BC557AP transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC557AP 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 BC557AP transistor as follows.
