DYNAMIC IMPEDANCE<br />

The Zener Impedance is derived from the 60Hz<br />

AC voltage which results when an AC current<br />

having an RMS value equal to 10% <strong>of</strong> the DC<br />

Zener current (lot or Izk) is superimposed on<br />

Izt or Izk. Zener Impedance is measured at two<br />

points to insure a sharp knee on the break<br />

down curve and eliminates unstable units.<br />
