Variables Used
Zener Current - (Measured in Ampere) - Zener Current is defined as the current passing through a zener diode when it is in operating mode.
Input Voltage - (Measured in Volt) - Input Voltage is defined as the voltage required at the input terminal of an electronic device to ensure the flow of current through it.
Zener Voltage - (Measured in Volt) - Zener Voltage is the threshold voltage at which a zener diode conducts current in reverse direction. It is determined by doping concentration of the diode.
Zener Resistance - (Measured in Ohm) - Zener Resistance is calculated when zener diode is operating in the breakdown region, i.e., the region where it is conducting current in reverse direction.

What is application of Zener diode?

Zener diodes are used for voltage regulation, as reference elements, surge suppressors, and in switching applications and clipper circuits. The load voltage equals breakdown voltage VZ of the diode. The series resistor limits the current through the diode and drops the excess voltage when the diode is conducting.

How to Calculate Zener Current?

Zener Current calculator uses Zener Current = (Input Voltage-Zener Voltage)/Zener Resistance to calculate the Zener Current, Zener current consists of a current limiting resistor connected in series with the input voltage with the Zener diode connected in parallel with the load resistor in this reverse biased condition. The stabilized output voltage is always selected to be the same as the breakdown voltage of the diode. Zener Current is denoted by Iz symbol.
