The KT209I is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the KT209I transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The KT209I 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 KT209I transistor as follows.
