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 10 mm from case are kept at ambient temperature (3) Measured with device junction in thermal equilibrium RATINGS AND CHARACTERISTIC CURVES 1N5225 THRU 1N5267
