BUL128DR8 NPN Transistor

The BUL128DR8 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUL128DR8 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUL128DR8 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 BUL128DR8 transistor as follows.
