Absolute Maximum Ratings *
* These ratings are limiting values above which the serviceability of the diode 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
