KTC4377 NPN Transistor

The KTC4377 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KTC4377 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KTC4377 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 KTC4377 transistor as follows.
