In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may

have to be derated. Maximum ambient temperature (TA(max)) is dependent on the maximum operating junction temperature (TJ(max)), the

maximum power dissipation of the device in the application (PD(max)), and the junction-to-ambient thermal resistance of the part/package

in the application (

JA), as given by the following equation: TA(max)= TJ(max)–(θJA X PD(max)).
