Tolerance and Type Number Designation. The Type Numbers Listed Have a Standard Tolerance on The Nominal Zener Voltage of 5%. 5. Zener Voltage (V ) Measurement. Guarantess The Zener Voltage When Measured at 90 Seconds While Maintaining The Lead Temperature (T ) at 25C Z L from The Diode Body. 6. Zener Impedance (Z ) Derivation. The Zener Impedance is Derived from The 60 Cycle AC Voltage, Which Results When an AC Current Having an rms Z Value Equal to 10% of The DC Zener Current (I or I ) is superimposed on I or I .
