8.1.1 Maximum loading dependent on switching frequency, line voltage and ambient temperature
The maximum permissible temperature for the rated current at rated voltage and rated clock frequency
is specified as rated temperature.
Since the dissipation of the power loss (heat development) in the device is decisively dependent on
the ambient temperature, the max. load must be reduced at an ambient temperature above the rated
temperature (see following table)!
The measured average value over 24 hours must be 5 K below the max. ambient temperature.
Since the power loss in the device increases with rising line voltage, the following table must be
observed.
