#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
