...
MMBZ5226B - MMBZ5257B Series Zeners
Tolerance: B = 5%
MMBZ5226B - MMBZ5257B Series
Absolute Maximum Ratings* TA = 25°C unless otherwise noted
Parameter Value Units
Storage Temperature Range -55 to +150
Maximum Junction Operating Temperature + 150
Total Device Dissipation
Derate above 25°C
*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 state limits. The factory should be consulted on applications involving pulsed
or low duty cycle operations.
