Fig.7 Vz = 6.8 thru 10 Volts
Fig.8 Vz = 12 thru 82 Volts
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
