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