SQ3019 NPN Transistor

The SQ3019 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the SQ3019 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The SQ3019 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 SQ3019 transistor as follows.
