AT270 PNP Transistor

The AT270 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the AT270 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The AT270 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 AT270 transistor as follows.
