A1255 PNP Transistor

The A1255 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the A1255 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The A1255 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 A1255 transistor as follows.
