STBD139T NPN Transistor

The STBD139T is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the STBD139T transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The STBD139T 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 STBD139T transistor as follows.
