TPD4S009: Why is the operating ambient temperature 85°C?

Part Number: TPD4S009
Other Parts Discussed in Thread: TPD4E1U06

Hi team,

I have a question about the operating ambient temperature (Ta) for this device.

Why is the maximum operating ambient temperature for the TPD4S009 85°C?

Devices like the TPD4E1U06 have a maximum of 125°C, and some devices can  up to 125°C, so please explain why the TPD4S009 is rated for 85°C.

Best Regards,

Shota
