2SD2171S NPN Transistor

The 2SD2171S is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 2SD2171S transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 2SD2171S 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 2SD2171S transistor as follows.
