KT647A-2 NPN Transistor

The KT647A-2 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KT647A-2 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KT647A-2 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 KT647A-2 transistor as follows.
