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, that operation at the maximum permitted

ratings could affect the reliability of the device.
