Notes: 1. The zener voltage (VZ) is tested under pulse condition of 15mS.  
The measured VZ is guaranteed to be within specification with device junction in thermal equilibrium.  
2. The device numbers listed have a standard tolerance on the nominal zener voltage of ±5%.  
3. 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 to IZT or IZK.  
4. Company reserves the right to improve product design , functions and reliability without notice.
