BF188 NPN Transistor

The BF188 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF188 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF188 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 BF188 transistor as follows.
