Tolerance and Type Number Designation. The type numbers listed 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 (V ) Measurement. Guarantees the zener voltage when measured at 90 seconds while z maintaining the lead temperature(T ) at 30 1C, from the diode body L 4. Zener Impedance (Z ) Derivation. The zener impedance is derives from the 60 cycle AC voltage, which results z when an ac current having and rms value equal to 10% of the DC zener current (I or I ) is superimposed on ZT ZK I or I ZT ZK 5. Surge Current (I ) Non-Repetitive. The rating list in the electrical characteristics table is maximum peak, non- R repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current, I per JEDEC registration however, actual device capability is as described in ZT Figure.10 2 Version: P2102
