Zener Current IZM (mA) 110 Notes : (1) The Zener impedance is derived from the 1 kHz AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (IZT) is superimposed on IZT. 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%.
