These ratings are limiting values above which the serviceability of the diode may be impaired.

Non-recurrent square wave PW= 8.3 ms, TA= 55 degrees C.

NOTES:

These ratings are based on a maximum junction temperature of 200 degrees C.

These are steady state limits. The factory should be consulted on applications involving pulsed

or low duty cycle operations.
