4.2 Operating conditions

☞ Unless otherwise indicated, all operating condition specifications are at an ambient temperature

of +25 °C.

⚠ Operation beyond the operating conditions is not recommended and extended exposure beyond

them may affect device reliability.

ΨM-A

Module-to-Ambient

thermal parameter

°C/W Thermal characterization parameter

ΨM-A = (TM – TA) / PH proportional to the temperature difference

between the internal temperature sensor of the module (TM) and

the ambient temperature (TA), produced by the module heat power

dissipation (PH), with the module mounted on a 79 x 62 x 1.41 mm 4-

Layer PCB with a high coverage of copper, in still air conditions

ΨM-C

Module-to-Case

thermal parameter

°C/W Thermal characterization parameter

ΨM-C = –TM - TC) / PH proportional to the temperature difference

between the internal temperature sensor of the module (TM) and

the ambient temperature (TC), produced by the module heat power

dissipation (PH), with the module mounted on a 79 x 62 x 1.41 mm 4-

Layer PCB with a high coverage of copper, with a robust aluminum

heat-sink and with forced air ventilation, i.e. reducing to a value

close to 0 °C/W the thermal resistance from the case of the module

to the ambient
