CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the

device at these or any other conditions above those indicated in the operational sections of this speciﬁcation is not implied.

NOTE:

1.

θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See

Intersil TB379.
