How Zener Regulators Work
A Zener diode can be used to create a simple voltage regulator circuit. When reverse-biased at its breakdown voltage (Vz), it maintains a nearly constant voltage across itself, even as the current changes. This calculator helps you find the appropriate series resistor (Rs) needed to limit the current through the diode and ensure it operates correctly. It also calculates the power dissipated by this resistor, which is crucial for selecting a component with a suitable power rating to prevent overheating.
