Note: 1. Type numbers listed have standard tolerance on the nominal zener voltage of ±5%.
2. Measured under thermal equilibrium and DC (I

3. The Zener impedance is derived from the 60Hz AC voltage which results when an AC current having an RMS value equal to 10%
of the Zener current (I

) is superimposed on I

. Zener impedance is measured at two points to insure a sharp knee
on the breakdown curve and to eliminate unstable units.
