D44R1 NPN Transistor

The D44R1 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the D44R1 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The D44R1 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 D44R1 transistor as follows.
