Notes:

1. Nominal Zener Voltage (VZ) is read with the device in standard test clips with 3/8- to 1/2-inch spacing between clip and case

of the diode. Before reading, the diode is allowed to stabilize for a period of 40 ±10 milliseconds at 25°C +8, -2°C.

2. The Zener Impedance (ZZ or ZZK) is derived from the 60 Hz ac voltage, which results when an ac current having an rms

value equal to 10% of the dc zener current (IZT or IZK) is superimposed on IZT or IZK, respectively.

3. The Surge Current (IZSM) is specified as the maximum peak of a nonrecurrent sine wave of 8.3 milliseconds duration.

4. Voltage regulation (DVZ) is the difference between the voltage measured at 10% and 50% of IZM.
