The zener voltage (V Z ) is tested under pulse condition of 1mS. 2. The device numbers listed have a standard tolerance on the nominal zener voltage of ±5%. 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 (I ZT or I ZK ) is superimposed to I ZT or I ZK. 4. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter voltage tolerances, contact your nearest Tak Cheong Electronics representative.
