BDX73 NPN Transistor

The BDX73 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BDX73 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BDX73 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 BDX73 transistor as follows.
