BD243A NPN Transistor

The BD243A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BD243A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD243A 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 BD243A transistor as follows.
