Notes: 

1. 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 measured at 90 seconds while maintaining the lead temperature(TL) at 30 ℃± 1°C, from the diode body 

4. Zener Impedance (Zz) Derivation. The zener impedance is derives from the 60 cycle AC voltage, which results when an ac current having and rms value equal to 10% of the DC zener current (IZT or IZK) is superimposed on IZT or IZK 

5. Surge Current (IR) Non-Repetitive. The rating list in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current, IZT per JEDEC registration; however, actual device capability is as described in Figure 10.
