NA21FI NPN Transistor

The NA21FI is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the NA21FI transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The NA21FI 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 NA21FI transistor as follows.
