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.
