Part Number: ISO7710-Q1
Hello, according datasheet the isolation barrier life is up to 40 Years, could you detail me under which condition (junction temperature, isolation voltage ...). Moreover is it possible to get the reliability report ?
Thank you for your help
The isolation barrier lifetime of an isolator is estimated through an industry standard test called Time Dependent Dielectric Breakdown (TDDB). Please see the image below that shows TDDB data for ISO7710-Q1 in WB SOIC-16 (DW) package.
The above plot shows how much time does the isolation barrier of ISO7710 can withstand a particular stress voltage at 1dppm fail rate. This test is done upto 150C of ambient temperature. The actual lifetime that you see from the plot is a lot more than 40 years but with margins we claim it at >40 years. That I believe answers your question, thanks.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

I'm sorry I misunderstood your question and was relating it to device lifetime. Please find below the reliability data for ISO7710-Q1. Thanks.
Usage temp : 55C ambient
Confidence level : 60%
Thank you very much for your feedback
