2 / 5 page  www.vishay.com 2 Document Number 85786 Rev. 1.4, 12-Dec-05 ZM4728A to ZM4764A Vishay Semiconductors Electrical Characteristics 1) The Zener impedance is derived from the 1 KH Z 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.
