ZT2857 NPN Transistor

The ZT2857 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the ZT2857 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The ZT2857 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 ZT2857 transistor as follows.
