KT209J PNP Transistor

The KT209J is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the KT209J transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KT209J 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 KT209J transistor as follows.
