Other Parts Discussed in Thread: ISO7231C, STRIKE

Hello

I would like to know the meaning of the below which cut from the Data sheet of ISO7231C.

What is different things Between 4000V-peak Isolation and 4kv ESD Protection?

PLeae let me know.

    Hi Jin,

    The 4KV Peak isolation rating is an isolation rating between GND1 and GND2. It is measured in AC voltage potential between the two grounds. Peak voltage is equal to the RMS voltage multiplied by the square root of two.

    When a device is certified (UL, CSA, VDE, etc.) it is tested for 60 seconds at this voltage. During production every device is tested at this voltage for 1 second.

    The 4kV ESD protection is a transient test per JEDEC standard. An ESD strike is different from an AC isolation voltage in that it is a transient voltage that lasts 10’s of ns, as opposed to a 60 second continuous test.

    Thanks,
