BC478QF PNP Transistor

The BC478QF is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BC478QF transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BC478QF 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 BC478QF transistor as follows.
