KT847B NPN Transistor

The KT847B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KT847B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KT847B 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 KT847B transistor as follows.
