= 25°C unless otherwise noted
* 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 200 degrees C.
2) These are steady limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
