KSA643Y PNP Transistor

The KSA643Y is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the KSA643Y transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KSA643Y 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 KSA643Y transistor as follows.
