Derating (thermal resist.) LXP100 /LXP100 L: 0.66 W/K (1.5 K/W)
Without a heat sink, when in open air at 25°C,the LXP100 /LXP100 L is rated for 3 W. Derating for temperature above 25°C is 0.023 W/K.
Case temperature must be used for definition of the applied power limit. Case temperature measurement must be done with a thermocouple contacting the center of the component mounted on the designed heat sink. Thermal grease should be applied properly.
This value is only applicable when using thermal conduction to heat sink Rth-cs
