The GT109D is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the GT109D transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The GT109D 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 GT109D transistor as follows.
