Figure 2. Derating Curves for RT9013 Packages
Where T
J(MAX)
is the maximum operation junction
temperature, T
A
is the ambient temperature and the
θ
JA
is
the junction to ambient thermal resistance.
For recommended operating conditions specification of
RT9013, where T
J(MAX)
is the maximum junction
temperature of the die (125
°
C) and T
A
is the operated
ambient temperature. The junction to ambient thermal
resistance
θ
JA
(
θ
JA
is layout dependent) for WDFN-6L 2x2
package is 165
°
C/W, SOT-23-5 package is 250
°
C/W and
SC-70-5 package is 333
°
C/W on the standard
JEDEC 51-3 single-layer thermal test board. The maximum
power dissipation at T
A
= 25
°
C can be calculated by
following formula :
P
D(MAX)
= (125

C) / 165 = 0.606 W for
WDFN-6L 2x2 packages

packages
P
D(MAX)
= (125

C
25
°
C) / 333 = 0.300 W for SC-70-5
packages
The maximum power dissipation depends on operating
ambient temperature for fixed T
J(MAX)
and thermal resistance
θ
JA
. For RT9013 packages, the Figure 2 of derating curves
allows the designer to see the effect of rising ambient
temperature on the maximum power allowed.
