result in failures not covered by warranty.
NOTES:
1.
JA
is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2.
JA
is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
3. For
JC
, the “case temp” location is the center of the exposed metal pad on the package underside.
