OC449K PNP Transistor

The OC449K is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the OC449K transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The OC449K 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 OC449K transistor as follows.
