BFY49R NPN Transistor

The BFY49R is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BFY49R transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BFY49R 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 BFY49R transistor as follows.
