Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.

best overall value.
4. The type numbers shown have a standard tolerance of ±5% on the nominal Zener Voltage.
5. Tolerance and Voltage Designation: Zener Voltage (VZ) is measured with the Zener Current applied for PW = 1 ms.
6. ZZT and ZZK are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are for
IZ(AC) = 0.1 IZ(DC), with the AC frequency = 1 kHz.
