Optimum reliability and life time are guaranteed if the junction temperature does not
exceed 125 °C in operating mode. Operation at up to the maximum junction temperature
of 150 °C is possible in principle. Note, however, operation at the maximum permitted
ratings could affect the reliability of the device.
