Environment

Operating temperature

-25°C to +70°C

The operational temperature is the ambient or surrounding temperature and is defined as the air temperature 2cm below the device.

Storage temperature

-40°C to +85°C

For storage and transport

Output derating

3.2W/°C
6W/°C
15W/1000m or 5K/1000m
9W/-5kPa or 3K/-5kPa

Between +45°C and +60°C
Between +60°C and +70°C
For altitudes >2000m see Fig. below
For atmospheric pressures <80kPa, see Fig. below

The derating is not hardware controlled. The customer must take care by himself to stay below the de-rated current limits in order not to overload the unit.
