For recommended operating conditions specification of
RT9014/A, 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 dependen
t) 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 T
A
= 25
°
C can be calculated by following formula :
P
D(MAX)
= ( 125
°
C
25
°
C ) / 108 = 0.926W for
WDFN-10L 3x
3 packages
The maximum power dissipation depends on operating
ambient temperature for fixed T
J(MAX)
and thermal
resistance
θ
JA
. 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.
