TLE 4268

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.
