Derating (thermal resistance): 0.23W/°K (4.28°K/W).
Without a heatsink, when in free air at 25°C, the MXP is rated for 2.50W. Derating for temp. above 25°C is 0.02W/°K. 




The case temperature is to be used for the definitiion of the applied power limit.
The case temperature measurement must be made with a thermocouple contacting the center of the component mounted on the designed heat sink.
Thermal grease should be applied properly.
