Part Number: UCD9081
My customer has the following question.
"Could you help me by providing additional information on the temperature rating on the UCD9081? It is rated with an Operating free-air temperature Spec of 85C with no maximum junction temperature specified on the datasheet. I would guess it has a recommended max junction specification of 125C, but I wanted to verify with you."
We are checking this and will update you soon.

In reply to yihe:
The inital resposne i got is that the Junction temp does not vary widely from the free-air temperature sine the device is very low poer and does not genertate much.
heat. so i would think 125C is too high.
Would 105C be OK?
In reply to Aaron Spaete:
The ambient T in many cases can be 85C. If that is the case, there is no way the Tj can stay at 85C as well. I would expect it to be hotter. Ideally we would be at 105C. Yes, this is an issue.
