Derating (thermal resist.) SUPT400: 5.65W/K (0.18 K/W)
Power rating: 400 W at 85°C bottom case temperature
This value is only applicable when using a thermal conduction to the heat sink Rth-cs<0.025K/W. This value can be obtained by using a thermal transfer compound with a heat conductivity of at least 1 W/mK. The flatness of the cooling plate must be better than 0.05 mm overall. Surface roughness should not exceed 6.4 μm.
