BF779 PNP Transistor

The BF779 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BF779 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF779 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 BF779 transistor as follows.
