*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.
