BFR91H NPN Transistor

The BFR91H is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BFR91H transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BFR91H 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 BFR91H transistor as follows.
