#1 This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load.
Remarks
*1 Measurement at same location as “Initial breakdown voltage” section. *2 Detection current: 10mA
*3 Wave is standard shock voltage of ±1.2 × 50μs according to JEC-212-1981 *4 Excluding contact bounce time.
*5 Half-wave pulse of sine wave: 11 ms; detection time: 10 μs *6 Half-wave pulse of sine wave: 6 ms
*7 Detection time: 10 μs
*8 The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to 1. Usage, transport and storage conditions in NOTES on page 3.
