Part Number: TPS546D24

I am trying to find out the recommended derating for the package and up to maximum current for the device. I see the maximum operating temperature for Tj is 150C which is also the absolute maximum Tj is 150C and the recommended Tj is also 150C. Does TI have a recommended derating for this product or family of products?

    The TPS546D24 is designed to operate reliably with die temperatures upto 150C.

    There are a number of SOA curves in the datasheet on page 14 and 15 http://www.ti.com/lit/ds/symlink/tps546d24a.pdf#page=14  the SOA curves are based on a 125C max die temperature, so they already include margin.
