DS_S48SE05003_12292006 9 Thermal Derating Heat can be removed by incr easing airflow over the module. T o e nhance system relia bility , the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected.
