STD127DT4 NPN Transistor

The STD127DT4 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the STD127DT4 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The STD127DT4 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 STD127DT4 transistor as follows.
