SK3218 NPN Transistor

The SK3218 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the SK3218 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The SK3218 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 SK3218 transistor as follows.
