Tolerance and type number designation the type numbers listed indicate a tolerance of 5% 2. Zener voltage (Vz) measurement Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature Zener impedance (Zz) derivation : Z ZT and Z ZK are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are for Iz(AC) =. Iz(DC) with the AC frequency = 6 Hz Document Number: DS_D4567 Version: H4
