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.

ZRM
(Maximum Zener Current Rating) Values shown are based on the JEDEC rating of 400 milliwatts. Where the actual zener voltage (VZ) is known at the
operating point, the maximum zener current may be increased and is limited by the derating curve.
