The Zener impedance is derived from the 1KHZ AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. 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 10 mm from case are kept at ambient temperature 3. Measured under thermal equilibrium and DC test conditions 02/15/2008 Rev.1.00 www.SiliconStandard.com 2 1N4728 thru 1N4764 RATINGS AND CHARACTERISTIC CURVES (TA=25 C unless otherwise noted) o Information furnished by Silicon Standard Corporation is believed to be accurate and reliable.
