Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

3. The type numbers shown have a standard tolerance of
5%
on the nominal Zener Voltage.
4. Tolerance and Voltage Designation: Zener Voltage (V
Z
) is measured with the Zener Current applied for PW = 1 ms.
5. 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 I

= 0.1 I
Z(DC),
with the AC frequency = 1 kHz.
