STC4081 NPN Transistor

The STC4081 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the STC4081 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The STC4081 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 STC4081 transistor as follows.
