Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. (2) Valid provided that leads at a distance of 3/8” from case are kept at ambient temperature. (3) The type number listed have a standard tolerance on the nominal zener voltage of ± 5.0%.
