The Zener Voltage ( VZ) is tested under pulse condition of 10mS. 2. The device numbers listed have a standard tolerance on the nominal zener voltage of ±2%. 3. 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 Electronics representative. 4. 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 (I ZT or IZK) is superimposed to IZT or IZK.
