D44U3 NPN Transistor

The D44U3 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the D44U3 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The D44U3 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 D44U3 transistor as follows.
