reliability and result in failures not covered by warranty.
NOTES:
4.
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
.
5. For
JC
, the “case temp” location is the center of the exposed metal pad on the package underside.
