SM2178 NPN Transistor

The SM2178 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the SM2178 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The SM2178 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 SM2178 transistor as follows.
