3DK40B NPN Transistor

The 3DK40B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 3DK40B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 3DK40B 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 3DK40B transistor as follows.
