The type numbers listed have a standard tlerance n the nminal zener vltage f ±5%. 2. Specials Available Include: A. Nminal zener vltages between the vltages shwn and tighter vltage tlerances. B. Matched sets. 3. Zener Vltage (VZ) Measurement. Guarantees the zener vltage when messured at 9 secnds while maintaining the lead temperature (TL) at 3 ± 1, frm the dide bdy. 4. Zener Impedance (ZZ) Derivatin. The zener impedance is derived frm the 6 cycle ac vltage, which results when an accurrent having and rms value equal t % f the dc zener current (IZT r IZK) is superimpsed n IZT r IZK. 5. Surge urrent (Ir) Nn-Repetitive. The rating listed in the electrical characteristics table is maximum peak, nn-repetitive, reverse surge current f 1/2 square wave r equivalent sine wave pulse f 1/1 secnd duratin superimpsed n the test current, IZT, per JEDE registratin; hwever, actual device capability is as described in Figure.
