The BFQ31A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BFQ31A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The BFQ31A 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 BFQ31A transistor as follows.
