Measured under thermal equilibrium and dc (I ) test conditions. ZT 4. The Zener impedance is derived from the 60 Hz ac voltage which results when an ac current having an rms value equal to 10% of the Zener current (I or I ) is superimposed on I or I . Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to ZT ZK ZT ZK eliminate unstable units. 1N4728A - 1N4761A DS18007 Rev. 19 - 3 2 of 3 Diodes Incorporated www.diodes.com
