Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only; and
functional operation of the device at these or any other condition beyond those indicated in the specifications is not implied. Exposure to absolute-
maximum-rated conditions for extended periods may affect device reliability. The thermal resistance and power dissipation ratings are measured under
board mounted and still air conditions. Ambient temperature (TA) is 25°C, unless otherwise specified.

1. Avalanche failures assumption:
Purely a thermal phenomenon and failure occurs at a temperature far in
excess of Tjmax. This is validated for every part type.

ployees, subsidiaries, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable
attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or
unauthorized use, even if such claim alleges that IR was negligent regarding the design or manufacture of the product.
Only products certified as military grade by the Defense Logistics Agency (DLA) of the US Department of Defense, are de-
signed and manufactured to meet DLA military specifications required by certain military, aerospace or other applications.
Buyers acknowledge and agree that any use of IR products not certified by DLA as military-grade, in applications requiring
military grade products, is solely at the Buyer’s own risk and that they are solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
IR products are neither designed nor intended for use in automotive applications or environments unless the specific IR
products are designated by IR as compliant with ISO/TS 16949 requirements and bear a part number including the designa-
tion “AU”. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, IR will
not be responsible for any failure to meet such requirements.
