BF274 NPN Transistor

The BF274 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF274 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF274 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 BF274 transistor as follows.
