Zener diode calculator | converters and calculators

This page of converters and calculators section covers zener diode calculator. This zener diode calculator calculates series resistance as output. It takes source voltage (min,max), zener diode voltage and load current (in mA) as input.

Source voltage, min(input1) :

Source voltage, max(input2) :

Zener voltage (input3) :

Load current,mA (input4) :


Series resistance in Ohms (Output1):

Example of zener diode calculator:
INPUTS : Vsmin = 20 V, Vsmax = 24 V, Vz = 12 V, IL (current through series resistor) = 500 mA
OUTPUTS: Zener series resistance = 16 Ohm.
