BUL49A NPN Transistor

The BUL49A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUL49A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUL49A 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 BUL49A transistor as follows.
