Notes:

1. Measured under thermal equilibrium and DC (I_ZT) test conditions.

2. 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_ZTor I_ZK) is superimposed on I_ZTor I_ZK. Zener impedance is measured at two points to insure a

sharp knee on the breakdown curve and to eliminate unstable units.
