KZT749 PNP Transistor

The KZT749 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the KZT749 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KZT749 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 KZT749 transistor as follows.
