Figure 3. Derating Curves for RT9011 Packages
For recommended operating conditions specification of
RT9011, 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
is layout dependent) for TSOT-23-6 package
is 220
°
C/W
and WDFN-8L 2x
2 is 165
°
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 - 25
°
C ) / 220 = 0.455 W for TSOT-23-6
packages
P
D(MAX)
= ( 125
°
C - 25
°
C ) / 165 = 0.606 W for
WDFN-8L 2x2
packages
The maximum power dissipation depends on operating
ambient temperature for fixed T
J(MAX)
and thermal
resistance
θ
JA
. For RT9011 packages, the Figure 3 of de-
rating curves allows the designer to see the effect of rising
ambient temperature on the maximum power allowed.
