BDT31AF NPN Transistor

The BDT31AF is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BDT31AF transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BDT31AF 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 BDT31AF transistor as follows.
