BUL5555 NPN Transistor

The BUL5555 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUL5555 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUL5555 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 BUL5555 transistor as follows.
