What Is a Zener Diode?

A Zener diode is a type of diode designed to protect electrical circuits from overvoltage conditions. It acts as a voltage regulating switch, providing a constant voltage output, no matter what input voltage fluctuations, that it may occur between. They are commonly used in switchmode power supplies, as these supplies are able to quickly change voltages. Zener diodes are able to protect the output from sudden overvoltage spikes and other voltage irregularities.
