BUL54B NPN Transistor

The BUL54B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUL54B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUL54B 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 BUL54B transistor as follows.
