ELECTRIC AL DATA
Table 2 Ele ctrica l data and orderi ng information
Notes
1. The sinusoidal voltage is assumed as the normal operating conditio n. If a non-sinusoidal voltage is present, type
selection should be based on multiplying the peak voltag e by a factor of 0.707.
2. The voltage measur ed at 1 mA meet s the requirem ents of “paragraph 4.3 of CECC spe cification 42000”.
3. The maximum non-repetitive surge current is given for one impulse 8 ×20 µs applied during the life of the component.
Figures 2 and 3 give the derating for different numbers and longer a duration of pulses.
4. A current wave of 8 ×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.
5. Energy is calculated by multiplying the pea k voltage , peak current and transient duration for a standard impulse
10 ×1000 µs (correction factor: ×1.4).
