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 are kept at ambient temperature (3) Tested under thermal equilibrium and DC test conditions RATINGS AND CHARACTERISTIC CURVES ZMM5225 THRU ZMM5267
