For recommended operating conditions specification of

RT9193, where TJ(MAX) is the maximum junction

temperature of the die (125

°C) and TA is the maximum

ambient temperature. The junction to ambient thermal

resistance (

θJA is layout dependent) for SOT-23-5 package

is 250

°C/W, SC-70-5 package is 333°C/W and WDFN-6L

2x2 package is 165

°C/W on standard JEDEC 51-3 thermal

test board. The maximum power dissipation at TA= 25

°C

can be calculated by following formula :

PD(MAX) = (125

°C−25°C) / 333 = 300mW (SC-70-5)

PD(MAX) = (125

°C−25°C) / 250 = 400mW (SOT-23-5)

PD(MAX) = (125

°C−25°C) / 165 = 606mW (WDFN-6L 2x2)

The maximum power dissipation depends on operating

ambient temperature for fixed TJ(MAX) and thermal

resistance

θJA. For RT9193 packages, the Figure 2 of

derating curves allows the designer to see the effect of

rising ambient temperature on the maximum power

allowed.
