BF108 NPN Transistor

The BF108 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF108 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF108 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 BF108 transistor as follows.
