BF181 NPN Transistor

The BF181 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF181 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF181 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 BF181 transistor as follows.
