NOTE:  
1. Tolerance and Type Number Designation. The type umbers 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 (Vz) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining  
the lead temperature (TL  
) at 30 oC + 1 oC, from the diode body.  
4. Zener Impedance (Zz) Derivation. 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 (Izt or Izk) is superimposed on Izt or Izk.  
5. Surge Current (Ir) Non-Repetitive. The rating listed in the electrical characteristics table is maximum peak,  
non-repetitive, reverse surge current of 1/2
