Operating and Storage Junction Temperature 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 temperature of 150 degrees C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
