BF422W3 NPN Transistor

The BF422W3 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BF422W3 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BF422W3 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 BF422W3 transistor as follows.
