The BFG21W is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BFG21W transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The BFG21W 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 BFG21W transistor as follows.
