A1273A PNP Transistor

The A1273A is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the A1273A transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The A1273A 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 A1273A transistor as follows.
