KTA1243 PNP Transistor

The KTA1243 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the KTA1243 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KTA1243 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 KTA1243 transistor as follows.
