AC521 PNP Transistor

The AC521 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the AC521 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The AC521 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 AC521 transistor as follows.
