## **Notes** 

> (1) The Zener impedance is derived from the 1 kHz AC voltage which results when an AC current having an RMS value equal to 10 % of the zener current (IZT1 or IZT2) is superimposed on IZT1 or IZT2. 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 

> (3) Measured under thermal equilibrium and DC test conditions 

> (4) Width of the test pulse is 8.3 ms
