Tolerance and Type Number Designation. The type numbers losted have a standard tolerance on the nominal zener voltage of ±5% 2. Specials Available Include: A. Nominal zener voltages between the voltages shown and tighter voltage tolerances B. Matched sets 3. Zener Voltage (Vz) Measurement. Guarantees the zener voltage when messured at 9 seconds while maintaining the lead temperature(t L ) at 3 ±, from the diode body 4. Zener Impedance (Zz) Derivation. The zener impedance is derives from the 6 cycle AC voltage, which results when an accurrent having and rms value equal to % of the DC zener current (I ZT or I ZK ) is superimposed on I ZT or I ZK 5. Surge Current (I R ) Non-Repetitive. The rating listd in the electrical chatacteristics table is maximum peak, non-repetitive, reverse surge current of /2 square wave or equivalent sine wave pulse of /2 second duration superimposed on the test current, I ZT per JEDEC registration; however, actual device capability is as described in Figure Version:E
