Power
rating
650W at 85°C bottom case temp. (Please ask for detailed
mounting procedure! This value is only applicable if using
thermal conduction to the heat sink Rth-cs<0.117°K/W.
This value can be obtained by using a thermal transfer
compound with a heat conductivity of 8.55 W/mK. The
flatness of the cooling plate must be better than 0.05mm
overall. Surface roughness should not exceed 6.4µm.
