BFQ43 NPN Transistor

The BFQ43 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BFQ43 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BFQ43 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 BFQ43 transistor as follows.
