  • RE: SN65HVD20: IEC 61000-4-2 ESD Ratings?

    Resolved
    Hi Kurt, Unfortunately this is not very straight-forward. You can make a rough approximation by comparing the total energy transfer of a certain JESD 22 (HBM) strike and finding the IEC 61000-4-2 strike level that would produce comparable levels. There…
