TLVH431A: Enquiry on Junction-to-ambient thermal resistance

Philip

Part Number: TLVH431A

Hi,

This is for TLVH431AQDCKR P/N (DCK Package).

My customer would like to understand why the Junction-to-ambient thermal resistance spec is smaller than Junction-to-case thermal resistance.

As per their understanding, Junction-to-ambient thermal resistance is always bigger than Junction-to-case. Is the thermal resistance spec information correct?

Please kindly help to advise, thanks.

Best Regards,

Philip

Hi Philip,

it seems the numbers are swapped. I am unsure on how this happened. the Rja should be 259 and Rjc should be 87.

I will work on getting this fixed on the next revision.

Hi Marcoo,

Thanks for the confirmation.

I will wait for the next revision before I submit the revised document for document approval.

Hi Philip,

Sounds good!

I will work on the revision but it will take a while for release.
