Thermal Ratings
Austin Power Modules are rated to operate in ambient
temperatures from –40°C to 80°C. The derating curves
below are provided as design aids for proper applica-
tion of the power modules. To insure adequate cooling,
the module temperature should be measured in the
system configuration. Ideally, temperature will be mea-
sured using an infrared temperature probe (such as the
FLUKE 80T-IR) or imaging system under the maximum
ambient temperature and the minimum air flow condi-
tions. Diode and FET case temperatures measured on
the top surface’s hottest spot should not exceed 105
°C. An alternative method of measuring temperature is
the use of thermocouples. For best results, a small
thermocouple should be attached to the leads of each
FET and diode using a small amount of cyanoacrylate
adhesive.
