3DD9E NPN Transistor

The 3DD9E is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 3DD9E transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 3DD9E 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 3DD9E transistor as follows.
