Notes On Page 2:
1. Tolerance and type number designation the type numbers listed indicate a tolerance of 5%
2. Zener voltage (Vz) measurement
Nominal Zener v oltage is measured with the device junction in thermal equilibrium with ambient temperature 25°C
3. Zener impedance (Zz) derivation : ZZT and ZZ K are measured by dividing the AC voltage
drop across the device by the AC current applied.
The specified limits are for Iz(AC) = 0.1 Iz(DC) with the AC frequency = 60 Hz
