Operating and Storage JunctionTemperature Range

*These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES: 1) These ratings are based on a maximum junction temperatureof 150 degrees C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
