For recommended operating conditions specification of

RT9014/A, where TJ(MAX) is the maximum junction

temperature of the die (125

°C) and TA is the operated

ambient temperature. The junction to ambient thermal

resistance (

θJA is layout dependent) for WDFN-10L 3x3

package is 108

°C/W on the standard JEDEC 51-3 single-

layer thermal test board. The maximum power dissipation

at TA = 25

°C can be calculated by following formula :

PD(MAX) = ( 125

°C − 25°C ) / 108 = 0.926W for

WDFN-10L 3x3 packages

The maximum power dissipation depends on operating

ambient temperature for fixed TJ(MAX) and thermal

resistance

θJA . For RT9014/A packages, the Figure 3 of

derating curves allows the designer to see the effect of

rising ambient temperature on the maximum power

allowed.
