Here is the reply I got back from the manufacturer ,
What I can get is this document. Basically the higher you go, the bigger the Rth will become and so power derating would be needed. , I do have the PDF document but cannot attach it to this forum post If you would send an email to applications.engineering@digikey.com I can get the document to you .

Thanks Craig
