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 attached.

Notes:
1. Tolerance and type number designation the type numbers listed indicate a tolerance of 5%
2. Zener voltage (Vz) measurement
Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature 25℃
3. Zener impedance (Zz) derivation : Z
ZT
and Z
ZK
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 = 60 Hz
