For recommended operating conditions specification of
RT9016, where T

is the maximum junction
temperature of the die (125

is the maximum
ambient temperature. The junction to ambient thermal
resistance (

is 250
°
C/W and WDFN-6L 2x2 package is 165
°
C/W on
standard JEDEC 51-3 thermal test board. The maximum
power dissipation at T

. For RT9016 packages, the Figure 3 of
derating curves allows the designer to see the effect of
rising ambient temperature on the maximum power
allowed.
