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 electrodes at a distance of 10mm from case are kept at ambient temperature (3) Measured under thermal equilibrium and DC test conditions RATINGS AND CHARACTERISTIC CURVES 1N4728 THRU 1N4764 1N4728 ... 1N4764 .
