K2121B NPN Transistor

The K2121B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the K2121B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The K2121B 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 K2121B transistor as follows.
