Hello Toshio-san,

Thanks for providing a picture, it helped us easily understand your question.

Yes, TMP411 will work when if the internal diode is designed such that Diode Cathode is grounded. If the the customer has a choice please advise him to not ground the cathode, otherwise there nothing to worry.

Thanks,

Abhi
