Notes
1. Lists with products certified according to UL (E98144), VDE (40002622) and CSA (219883) are available at www.vishay.com or on request.
2. The sinusoidal voltage is assumed as the normal operating condition. If a non-sinusoidal voltage is present, type selection should be based
on multiplying the peak voltage by a factor of 0.707.
3. The voltage measured at 1 mA meets the requirements of “paragraph 4.3 of CECC specification 42000”.
The tolerance on the voltage at 1 mA is ±10%.
4. High energy surges are generally of longer duration. The maximum energy for one pulse of 10 × 1000 µs is given as a reference for longer
duration pulses. This pulse can be characterised by peak current (Ip) and pulse width t2 (virtual time of half Ip value, following “IEC 60060-2,
section 6” ). If Vp is the clamping voltage corresponding to Ip, the energy absorbed in the varistor is determined by the formula:
E = K × Vp × Ip × t2
where:
a) K is dependant on the value of t2 when the value of t1 is between 8 µs and 10 µs; see Peak Current as a Function of Pulse Width drawing.
5. A current wave of 8 x 20 µs (requirement of “paragraph B.2.10.1 of CECC specification 42000” ) is used as a standard for pulse current and
clamping voltage ratings. The maximum non-repetitive transient current is given for one pulse applied during the life of the component.
