The Zener Voltage (V Z ) is tested under pulse condition of ms. 2. The device numbers listed have a standard tolerance on the nomial zener voltage of ±5%. 3. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter voltage tolerances, contact your nearest 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 % of the dc zener current(i ZT or I ZK ) is superimposed to I ZT or I ZK.
