MM1943 NPN Transistor

The MM1943 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MM1943 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MM1943 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 MM1943 transistor as follows.
