BU125 NPN Transistor

The BU125 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BU125 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BU125 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 BU125 transistor as follows.
