BF155 NPN Transistor

The BF155 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF155 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF155 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 BF155 transistor as follows.
