Optimum reliability and lifetime can be ensured in integrated circuits by not exceeding a
junction temperature of 125 °C during operation. Although operation up to the maximum
permissible junction temperature of 150 °C is possible, such boundary conditions, if
sustained, may affect device reliability.
