ENVIRONMENTAL CONDITIONS

To determine the junction temperature on the application

printed circuit board use:



where:

TJ = Junction temperature (°C)

TCASE = Case temperature (°C) measured by customer at top

center of package.



JT = From Table 68

PD = Power dissipation (see Total Internal Power Dissipation on

Page 56 for the method to calculate PD)

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:



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.

In Table 68, airflow measurements comply with JEDEC stan-

dards JESD51-2 and JESD51-6. The junction-to-case

measurement complies with MIL-STD-883 (Method 1012.1).

All measurements use a 2S2P JEDEC test board.
