OC78N PNP Transistor

The OC78N is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the OC78N transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The OC78N 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 OC78N transistor as follows.
