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.
θ
JA
is measured with the component mounted on an evaluation PC board in free air.
2. Characterized with 2 x 10µs, and 10 x 1000µs first level lightning surge waveforms (GR-1089-CORE).
3. These parameters are controlled via design or process parameters and are not directly tested. These parameters are characterized upon initial
design release and upon design changes which would affect these characteristics.
