BUL54A NPN Transistor

The BUL54A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUL54A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUL54A 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 BUL54A transistor as follows.
