KC149 NPN Transistor

The KC149 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KC149 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KC149 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 KC149 transistor as follows.
