Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage. From that point on, the low impedance of the diode keeps the voltage across the diode a… WebStep 3: Zener Diodes Zener diodes are doped with a higher concentration of impurities to give them a very thin depletion layer. In use they are reverse biased. This means that current cannot move across a zener diode until the breakdown voltage is reached.

WebThis calculator calculates the series resistance of a Zener diode. The resistance must be dimensioned that the total current does not pull down the output voltage. A minimal current has to flow through the Zener diode for the stabilization to work. As a guide value, 10% of the load current or 10 mA can be assumed.
