The data of SOA curve is base on Tj(pk) = 200°C; TC is variable depending on conditions. Second breakdown pulse limits are valid for duty cycles to 10% provided Tj(pk) = 200°C, At high case temperatures, thermal limitation will reduce the power that can be handled to values less than the limitations imposed by second breakdown.
