KFS20 NPN Transistor

The KFS20 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the KFS20 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The KFS20 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 KFS20 transistor as follows.
