BD239D NPN Transistor

The BD239D is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BD239D transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BD239D 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 BD239D transistor as follows.
