The device numbers listed have a standard tolerance on the nominal zener voltage of 5%. 2. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter voltage tolerances. 3. The zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an ms value equal to 10% of the dc zener current (I or I ) is superimposed to I or I .
