GF122 PNP Transistor

The GF122 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the GF122 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The GF122 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 GF122 transistor as follows.
