About insulation guarantee

ADuM1440'S Data Sheet ,Table 18 shows . Maximum Continuous Working Voltage1

I want to know that table18's guarantee is under Tj<150 ℃ (useing table 17 condition)?

    Hello OTI,

    We maintain UL certification to UL1577 to address US electric code requirements.  You can download this certification on our web site, there is a link from the product page..

    All parameters are guaranteed over the full operating temperature.  The insulation can actually survive higher temperatures than the max junction temperature without deterioration.  The mold compound upt tpo about 300C and the polyimide up to about 500C.  Based on this we could provide such a letter, but we would rather utilize the available documentation.

    Is this an Intrinsic Safety application?  If so we will have an ATEX certification on this device shortly.

    Best Regards,
