NOTE 3. ZENER VOLTAGE (Vz) MEASUREMENT

Nominal zener voltage is measured with the device function in thermal equilibrium with ambient

temperature at 25 C

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
