BU931R NPN Transistor

The BU931R is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BU931R transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BU931R 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 BU931R transistor as follows.
