ENVIRONMENTAL CONDITIONS
To determine the junction temperature on the application
printed circuit board use:
where:
T
J
= Junction temperature ( C)
T
CASE
= Case temperature ( C) measured by customer at top
center of package.
Ψ
JT
= From
Table 33
P
D
= Power dissipation (see
Power Dissipation on Page 41
for
the method to calculate P
D
)
Values of
θ
JA
are provided for package comparison and printed
circuit board design considerations.
θ
JA
can be used for a first
order approximation of T
J
by the equation:
where:
T
A
= Ambient temperature ( C)
In
Table 33
, airflow measurements comply with JEDEC stan-
dards JESD51-2 and JESD51-6, and the junction-to-board
measurement complies with JESD51-8. The junction-to-case
measurement complies with MIL-STD-883 (Method 1012.1).
All measurements use a 2S2P JEDEC test board.
Thermal resistance
θ
JA
in
Table 33
is the figure of merit relating
to performance of the package and board in a convective envi-
ronment.
θ
JMA
represents the thermal resistance under two
conditions of airflow.
θ
JB
represents the heat extracted from the
periphery of the board.
Ψ
JT
represents the correlation between
T
J
and T
CASE
. Values of
θ
JB
are provided for package compari-
son and printed circuit board design considerations.
