KT945B NPN Transistor

The KT945B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KT945B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KT945B 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 KT945B transistor as follows.
