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.

3. Zener voltage is measured with the device junction in thermal equilibrium with an ambient temperature of 25
°
C.
4. Zener Impedance Derivation Z
and Z
are measured by dividing the AC voltage drop across the device by the AC current applied. The
specified limits are for I
(ac) = 0.1 I
(dc) with the ac frequency = 60 Hz.
* The “G” suffix indicates PbFree package available.
