PT519 NPN Transistor

The PT519 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the PT519 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The PT519 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 PT519 transistor as follows.
