BD643F NPN Transistor

The BD643F is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BD643F transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD643F 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 BD643F transistor as follows.
