I have a question for ADuM5000 DC isolation voltage.

The requirement from the customer is DC isolation voltage 3000V. 

And my assumption is as follow. Is this correct?

 

[My assumption]:

ADuM5000 Isolation voltage is 2500V rms at 1 min.

But each ADuM5000W is proof tested by applying an insulation test voltage ≥ 3000 V rms for 1 sec(page5 on the  data sheet  ,comment 1)

The wave form of these test is bipolar AC , but the performance for DC is better than bipolar AC.

So, ADuM5000 meet isolation voltage for DC 3000V at 1sec.

 

Best regards
