BD546A PNP Transistor

The BD546A is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BD546A transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD546A 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 BD546A transistor as follows.
