DERATING
Derating (thermal resistance): 0.23W/°K (4.28°K/W). The case temperature is to be used for
purposes of establishing 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 propperly.
