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.
*
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.
