This value is only valid by using a thermal conduction to the heatsink Rthcs<0.025°K/W. This value can be reached by using thermal transfer compound with a heat conductivity of 1W/mK. The flatness of the cooling plate must be better than 0.05mm overall. The roughness of the surface should not exceed 6.4µm. 10,000 100,000 0 0 25 50 100 125 75 Case temperature, °C 150 175 0 11,500 1,150 O R D E R I N G I N F O R M AT I O N RoHS compliant Non-compliant version unavailable 115 11.5 1 TA P 8 0 0 K 5 R 0 E Style Wattage Tolerance 800 watts J = 5% K = 10%, Std.
