GF138 PNP Transistor

The GF138 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the GF138 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The GF138 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 GF138 transistor as follows.
