BFY44 NPN Transistor

The BFY44 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BFY44 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BFY44 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 BFY44 transistor as follows.
