The GFT21-15 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the GFT21-15 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The GFT21-15 transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.
