Organization: IEEE
Publication Date: 7 December 2016
Status: active
Page Count: 46
scope:

This standard covers test methods and performance values for metal-oxide varistor (MOV) surge protective components (SPCs) with the following main parameter ranges:

- Packaging: Leaded disc-type or surface mount

- Nominal varistor voltage: 5 V to 1200 V

- 8/20 surge current rating: 10 A to 70 kA

- 8/20 clamping voltage: 10 V to 3 kV

With appropriate component selection, these components could be used for the overvoltage protection of power and signal systems having the following:

- Continuous ac voltages: 2.5 V rms to 750 V rms

- Steady-state dc voltages: 3.3 V to 1000 V

- Peak signal feed voltages: 3.5 V to 850 V

Information is given on manufacturer type testing used to determine environmental performance and rated values.
