Notes:
1. 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 25°C
3. Zener impedance (Zz) derivation : ZZT and ZZK are measured by dividing the AC voltage drop across the device by the AC current applied.
4. The specified limits are for Iz(AC) = 0.1 Iz(DC) with the AC frequency = 60Hz
