UPT523 NPN Transistor

The UPT523 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the UPT523 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The UPT523 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 UPT523 transistor as follows.
