Note:
4. Tolerance and Type Number Designation. The Type Numbers Listed Have a Standard Tolerance on The Nominal Zener Voltage of ±5%.
5. Zener Voltage (VZ) Measurement. Guarantess The Zener Voltage When Measured at 90 Seconds While Maintaining The Lead Temperature (TL) at 25°C
from The Diode Body.
6. Zener Impedance (ZZ) Derivation. The Zener Impedance is Derived from The 60 Cycle 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.
