ET4040 NPN Transistor

The ET4040 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the ET4040 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The ET4040 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 ET4040 transistor as follows.
