ENVIRONMENTAL CONDITIONS
To determine the junction temperature on the application
printed circuit board use:
TJ = TCASE + JT PD
where:
TJ = Junction temperature (°C)
TCASE = Case temperature (°C) measured by customer at top
center of package.
JT = From Table 66
PD = Power dissipation — For a description, see Total Power
Dissipation on Page 35.
Values of JA are provided for package comparison and printed
circuit board design considerations. JA can be used for a first
order approximation of TJ by the equation:
TJ = TA + JA PD
where:
TA = Ambient temperature (°C)
Values of JC are provided for package comparison and printed
circuit board design considerations when an external heat sink
is required.
Values of JB are provided for package comparison and printed
circuit board design considerations.
In Table 66, 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.
