BD539 NPN Transistor

The BD539 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BD539 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD539 transistor symbol shows an arrow from the base into the emitter. This means that the current flows from collector terminal to emitter terminal.

Circuit diagram symbol of the BD539 transistor as follows.
