BUT18AF NPN Transistor

The BUT18AF is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUT18AF transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUT18AF 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 BUT18AF transistor as follows.
