2N2445 PNP Transistor

The 2N2445 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the 2N2445 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 2N2445 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 2N2445 transistor as follows.
