BUL49B NPN Transistor

The BUL49B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUL49B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUL49B 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 BUL49B transistor as follows.
