Hello,
It seems like there is some conflicting information about the maximum temperature allowed during operation of this device. The description in section 3 and the electrical characteristics in table 7.8 indicate a rating up to 125 C ambient temperature, while section 7.3 specifies recommended operation with a maximum junction temperature of 125 C. If both of these are true, then it would imply that no power dissipation is allowed at its maximum ambient operating temperature.
We have an condition where we believe that the device can get to approximately 134 C junction temperature (104 C case temperature). Does this actually violate the datasheet? If so, then can you provide any more information about operation in this mode between the recommended operating condition (125 C junction temperature) and the absolute maximum rating (150 C junction temperature)?
