UPT321 NPN Transistor

The UPT321 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the UPT321 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The UPT321 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 UPT321 transistor as follows.
