NOTES:

(1) The Zener impedance is derived from the 1KH Z AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (I ZT or I ZK)

is superimposed on I ZT or I ZK. 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
