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 operations.
