GFT21R PNP Transistor

The GFT21R is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the GFT21R transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The GFT21R 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 GFT21R transistor as follows.
