KZT1149A PNP Transistor

The KZT1149A is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the KZT1149A transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KZT1149A 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 KZT1149A transistor as follows.
