Notes: 

- *1:  No suffix indicates a ±20% tolerance on nominal Vz. Suffix A denotes a ±10% tolerance, B denotes a ±5% tolerance, C denotes a ±2% tolerance, and D denotes a ±1% tolerance. 

- *2: Zener voltage (Vz) is measured at TL=30°C. Voltage measurement to be performed 90 seconds after application of dc current. 

- *3:  The zener impedance is derived from the 60Hz ac voltage, which results when an ac current having an r ms value equal to 10% of the dc zener current(IZT or IZK) is superimposed on IZT or IZK.
