SQ5109 NPN Transistor

The SQ5109 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the SQ5109 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The SQ5109 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 SQ5109 transistor as follows.
