3DK9 NPN Transistor

The 3DK9 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 3DK9 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 3DK9 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 3DK9 transistor as follows.
