Operational temperature
-25°C to +70°C (-13°F to 158°F)
The operational temperature is the ambient or
surrounding temperature and is defined as the
air temperature 2cm below the device.

The derating is not hardware controlled. The customer has to take care by himself to
stay below the derated current limits in order not to overload the unit.
