*These ratings are limiting values above which the serviceability of the diode may be impaired.
**Non-recurrent square wave PW= 8.3 ms, TA= 50 degrees C.
NOTES:
1) These ratings are based on a maximum junction temperature of 200 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed
or low duty cycle operations.
