40217 NPN Transistor

The 40217 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 40217 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 40217 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 40217 transistor as follows.
