BUF420AW NPN Transistor

The BUF420AW is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUF420AW transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUF420AW 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 BUF420AW transistor as follows.
