*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.  
DO-41  
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.
