NA21Z NPN Transistor

The NA21Z is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the NA21Z transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The NA21Z 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 NA21Z transistor as follows.
