BF454B NPN Transistor

The BF454B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF454B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF454B 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 BF454B transistor as follows.
