BF393K NPN Transistor

The BF393K is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF393K transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF393K 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 BF393K transistor as follows.
