NOTE 3. ZENER VOLTAGE (Vz) MEASUREMENT  
Nominal zener voltage is measured with the device function in thermal equilibrium with ambient  
temperature at 25OC  
NOTE 4. ZENER IMPEDANCE (Zz) DERIVATION  
Zzt and Zzk are measured by dividing the ac voltage drop across the device by the accurrent applied.  
The specified limits are for Iz(ac) = 0.1 Iz, (dc) with the ac freqency = 60Hz
