HOW TO SELECT METAL OXIDE VARISTORS
• What is the range of ACrms or DC Voltage in the application?
• How will the varistor be connected in the circuit?
• Calculate the required varistor voltage at 10% to 25% above the system RMS or DC Voltage.
• Calculate the varistor energy rating needed based on energy in transient voltage.
• Calculate the surge current wave form from the surge voltage and surge impedance.
• Check to make sure the withstanding surge current of the varistor is sufficient.
P Type Y Type (most popular)
• Check whether the maximum energy and surge life of the varistor is enough.
• Check the relation:
