BDW21C NPN Transistor

The BDW21C is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BDW21C transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BDW21C 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 BDW21C transistor as follows.
