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 are kept at ambient temperature. 5) Measured under thermal equilibrium and DC test conditions. 143 ITT SEMICOND/ INTERMETALL 63E D MM 4682711 0003208 279 MBISI ZM4729 .. .
