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 tighte r voltage tolerances, contact your nearest Tak Cheong’s representative. 3. The zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed to IZT or IZK.
