PN3721 NPN Transistor

The PN3721 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the PN3721 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The PN3721 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 PN3721 transistor as follows.
