Junction temp confirmation

您好，

已经收到了您的案例，调查需要些时间，感谢您的耐心等待。

I see the temperature in the Spec.

But what i want to confirm if they are wrong in the spec.

Like TPA3255 and TPA3223, the OTE is about 155degC, why TJ max  is 125degC?   

And for TPA3223, the lowest Juntion temp is 0degC not -40degC?

Hi wenjie,

 For all of the device max temperature, please all use OTSD value as max supported junction temperature.

 TPA3223 seems not an automotive part, may not fully support to -40C working.

Hi 

As I check this device's design target still take -40C as minimum working range.

But it's already not our group's device, let me transfer to other team, to see if they have any further commence.

Any update for other team's comments?
