KT817B9 NPN Transistor

The KT817B9 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KT817B9 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KT817B9 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 KT817B9 transistor as follows.
