5. Tolerance and Voltage Designation: Zener Voltage (VZ) is measured with the Zener Current applied for PW = 1 ms.
6. 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.
