(3) The type number listed have a standard tolerance on the nominal zener voltage
(1) The Zener impedance is derived from the 1KHz AC voltage which results when an AC current having an RMS value equal
(2) Valid provided that electrodes at a distance of 10mm from case are kept at ambient temperature
