BD239E NPN Transistor

The BD239E is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BD239E transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD239E 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 BD239E transistor as follows.
