2DD2678 NPN Transistor

The 2DD2678 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 2DD2678 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 2DD2678 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 2DD2678 transistor as follows.
