Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. Measured at ambient temperature at a distance of 9.5mm from the case. 3. Short duration test pulse used to minimize self-heating effect.
