Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only, and function operation of the device at these or any other conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute‐maximum–rated conditions for extended periods may affect device reliability.
Caution: Stress above the listed absolute maximum rating may cause permanent damage to the device. * HBM B: 2000V to 3999V
