Calculation of a resistor for a zener diode
This calculator will help you calculate the resistor for a zener diode. For calculation, it is necessary to specify the supply voltage, the zener diode stabilization voltage, the minimum zener diode stabilization current and the current consumed by the load.
The figure below shows a diagram of a simple parametric stabilizer on a zener diode and a resistor.
A simple parametric stabilizer is based on a semiconductor element known as a zener diode. It operates in the mode of electrical breakdown on the reverse branch of the volt-ampere characteristic, when the supply voltage changes, the current flowing through the zener diode changes, and the voltage on it remains constant.
In order for the zener diode to work correctly, it must be connected in the opposite direction.
