Environment

Operating temperature

-25 °C...+70 °C

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

Storage temperature

-40 °C...+85 °C

For storage and transport

Power derating

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

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