Hello friends, I hope you all are doing great. Today, I am going to share the new Zener Diode Library for Proteus . Every diode has a limit: push enough voltage across it backwards and it breaks down. In most diodes that is the end of the story. A Zener diode is built to do this on purpose, at a precise voltage, and to survive it all day long. That makes it the simplest voltage regulator in electronics.
