ZENER VOLTAGE (Vz) MEASUREMENT Nominal zener voltage is measured with the device function in thermal equilibrium with ambient O 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 STAD-NOV.05.2004 PAGE . 4
