3. The type numbers shown have a standard tolerance of 5% on the nominal Zener Voltage.
4. Tolerance and Voltage Designation: Zener Voltage (V ) is measured with the Zener Current applied for PW = 1 ms.
Z
5. Z and Z are measured by dividing the AC voltage drop across the device by the AC current applied.
ZT ZK
The specified limits are for I = 0.1 I with the AC frequency = 1 kHz.
