Tolerance and Type Number Designation. The type umbers listed have a standard tolerance on the nominal zener voltage of + 5% 2. Specials Available Include: A. Nominal zener voltages between the voltages shown and tighter voltage tolerances. B. Matched sets. 3. Zener Voltage (Vz) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining o o the lead temperature (T L ) at 30 C + 1 C, from the diode body. 4. Zener Impedance (Zz) Derivation. The zener impedance is derived from the 60 cycle ac voltage, which results when an .
