The type numbers listed have a standard tolerance on the nominal zener voltage of 5% for 'B' and 10% for 'A 2.Specials Available Include: A. Nominal zener voltages between the voltages shown and tighter voltage t olerances. B. Matched sets. 3. Zener Voltage (VZ) Measurement. Guarantees the zener volt age when measured at 90 seconds while maintaining the lead the t emperature (TL) at 30 , from the diode body. C 4. Zener Impedance (ZZ) Derivation. The zener impedanc e is derived from the 60 cycle ac voltage, which resul ts 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 5. Surge Current (IR) Non-Repetitive. The rating listed in the el ectrical characteristics table is maximum peak, non-repetit ive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on t he test current, IZT, per JEDEC regis tration; however, actual device capability is as described in Figure 5.
