AC191 PNP Transistor

The AC191 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the AC191 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The AC191 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 AC191 transistor as follows.
