BC258A PNP Transistor

The BC258A is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BC258A transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC258A 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 BC258A transistor as follows.
