MJE1909 NPN Transistor

The MJE1909 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the MJE1909 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MJE1909 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 MJE1909 transistor as follows.
