## **Absolute Maximum Ratings *** TA = 25°C unless otherwise noted 

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

## **NOTES:** 

1) These ratings are based on a maximum junction temperature of 150 degrees C. 

2) These are steady limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
