Part Number: DM3730
We are using the specified device (DM3730CUSD100) in our application.
Looking at table 3-3 under the OPP130 col for 105C there is no information available, do you have any?
We might have a case where we use the industrial component with junction temperature exceeding 90C (Lets say 92-95C for short time periods - seconds), do you know if the possible damage to the life time of the device is addative? (Other way to ask it if the device only partially works at high junction temperature what are the risks?
Is table 3-3 valid for the extended temperature range or only for the industrial?
Should I worry about using the industrial devices for few seconds at ~95C?
Another question is what is the difference between the extended temp range and the industrial devices? Is it produced in the same line and the difference is tests only?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Cvetolin Shulev-XID:
Can you please elaborate about the differences between the industrial and extended temperature range devices manufacturing process?
Is the difference derived from tests only or does the manufacturing process different?
In reply to Eli az:
I am asking this question because of the difference in the reliability reports over time.
A few years ago in 2014 I got a reliability report with 3 fails of the industrial device with 0.5keV activation energy.
The reliability report of the extended temp range now is for 0.7keV.
This is why I want to know if there are different processes for both or if the upgrade to the extended temp range is transperent?
In reply to sivak:
The reliability data was taken from TI website.
The reliability data is for DM3730CUSD100, Usage temp of 55C, 60% Confidence level, 0.5eV activation energy, Test temp of 130C, Test duration of 1000h for 1790 samples with 3 fails.
The main thing I want to know is what test I have to do changing the industrial temperature range to the extended temperature range.
If both devices is manufactured in the same process and then sorted so this change in device temperature range is transparent.
Currently my application is heating too much and I can keep the industrial temperature range.
