40239 NPN Transistor

The 40239 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the 40239 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The 40239 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 40239 transistor as follows.
