BD124 NPN Transistor

The BD124 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BD124 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD124 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 BD124 transistor as follows.
