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 .
