The KN3903S is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KN3903S transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.
The KN3903S transistor symbol shows an arrow from the base into the emitter. This means that the current flows from collector terminal to emitter terminal.
