BUW77 NPN Transistor

The BUW77 is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the BUW77 transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BUW77 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 BUW77 transistor as follows.
