2SD1621U NPN Transistor

The 2SD1621U is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 2SD1621U transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 2SD1621U 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 2SD1621U transistor as follows.
