     ・CANADA/CSA   IEC 60950-1 2nd Edition

     ・Thermal cycling test

 

Best regards

    Seishin,

    For all of our isolation products, there is a section titled 'More Literature' on the product page that contains certification information. Here is the link to that section for ISO7241M

    http://www.ti.com/product/iso7241m#doctype5

    There is a link to the CSA certification at that location (http://www.ti.com/litv/pdf/szzq071d). You will find on page 1 of that document that ISO7241 has been certified to 4kV peak isolation according to IEC60950-1 2nd Ed.

    Page 7 of that document explains the thermal cycling testing done to the ISO7242, which is essentially the same part with a 2/2 channel configuration instead of a 3/1 in the ISO7241. One sample was subjected to 10 cycles of the following: 68h at 135C, 1h at 25C, 2h at 0C, and 1h at 25C. After cycling, the sample passed a dielectric strength test of 2935Vrms, 60Hz, 60s.

    I hope this helps answer your questions!

    Thanks,
    Jason Blackman

    Hello, I checked the contents of CSA certification report for the inquiry that Seishin asked.

     

    I could not find out the description below on Project: 2514508 for ISO7241M.

    4. Evaluated by thermal cycling and other tests for a temperature rating of 125C.

     

    Instead, this description was found on other projects, such as Project: 2557796, 2557795 and etc..

    I suppose that the thermal cycling was certificated on Project: 2557796 for ISO742X series, not ISO724X.

    Could you let me clarify once again whether ISO724X series were certificated on this matter?

     

    Thank you once again for your information.

     

    Best regards,

    Atsushi,

    My apologies, the document on the web isn't the same one I was looking at when I responded to your post. Here is the full certificate for the ISO7241:

    0447.CSA Report_ISO723x_724x_A_C_CF_M.pdf

    This should clear things up.

    Thanks,
    Jason
