Where
Ψ
JT is the junction-to-package top thermal characterization parameter. If the case
temperature exceeds the specified Tcase max, thermal enhancements such as heat sinks or forced air
will be required. In the tables below,
Θ
JA is the package junction-to-air thermal resistance.

Absolute Maximum Ratings
Warning:
Stressing the device beyond the “absolute maximum ratings” may cause permanent damage. These
are stress ratings only. Operation beyond the “operating conditions” is not recommended and
extended exposure beyond the “operating conditions” may affect device reliability.
