Definition of Terms (according to IEEE specifications C62.33)

Average Power Dissipation: Tested using two consecutive pulses at rated peak current using a 10/1000µs test

waveform with a minimum pulse period of 60 seconds between pulses (IEC 61000-4-5).

Rated RMS Voltage, Rated DC Voltage: The maximum designated values of power system voltage that may be applied

continuously between the terminals of a device.

Varistor Voltage: Test characteristic that is used to classify varistors by type. A test current of 1mA DC is typically

used to determine varistor voltage classification type. Varistor voltage clamping characteristics can be defined

at various test levels.

Rated Peak Single Pulse Transient Current: Maximum surge current, 8/20μs waveform which a varistor is rated to

withstand for a single surge.

Rated Single Pulse Transient Energy: Maximum allowable energy for a single impulse (see specified waveforms).

Maximum Clamping Voltage: Measured peak voltage across the device terminals when a current impulse of specified

amplitude and waveform is conducted through the varistor.

Typical Capacitance: Typical capacitance values are measured at a test frequency of 1KHZ.

General Characteristics

- 55° C to + 125° C

Operating Surface Temperature

125° C

Operating Ambient Temperature

- 55° C to + 85° C (without derating)

Maximum Voltage-Temperature

Coefficient

< -0.01 % / °C

Insulation Resistance

1000 Megohm min.

Hi POT (Leads to Case, 1 min.)

3000 VDC*

Typical Response Time

Failure Criteria

Voltage change ± 10% from initially measured Varistor Voltage. When

determining if varistor is within aforementioned criteria the same temperature

must be observed as was used for initial Varistor Voltage measurements.

*Rating is for standard epoxy, for flame retardant coating (suffix “S”) disk sizes 5mm to 20mm rating is 2000 VDC, for disk

sizes 22mm & 34mm rating is 2500VDC.
