I read this great articles on ESD basics (https://e2e.ti.com/blogs_/b/powerhouse/archive/2017/12/06/esd-fundamentals-part-3-clamping-voltage ) , and I left my questions below. But I am not sure whether the author is still work at TI , so I post my question here to discuss together.
The author mentioned we could use ESD122 TLP curves to get accurate Vclamp value under certain current vaule, and he listed that 2/4/6/8kV IEC strike correspond to 4/8/12/16A TLP currents.(as marked in below picture).
I really want to consult how do we get this relationship : IEC Voltage strike (kV) x2 equals TLP currents ?
PS：I refer to 61000-4-2, the correct data should be 7.5/15/22.5/30A Ipp current correspond to 2/4/6/8kV IEC strike .
