MMBT3904K NPN Transistor

The MMBT3904K is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MMBT3904K transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MMBT3904K 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 MMBT3904K transistor as follows.
