KT665B9 NPN Transistor

The KT665B9 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KT665B9 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KT665B9 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 KT665B9 transistor as follows.
