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)?
or limited condition?
Thank you for an answer.
My reuquest document is not CSA/SIRA.
You send me letter
"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.
Please give me the contents mentioned above with a file.
The reason is:
