BD501B NPN Transistor

The BD501B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BD501B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD501B 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 BD501B transistor as follows.
