Note:
1. The Zener impedance is derived from the 1KHZ 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 10mm from case are kept at ambient temperature
3. Measured under thermal equilibrium and DC test conditions
