KT8109B NPN Transistor

The KT8109B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KT8109B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KT8109B 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 KT8109B transistor as follows.
