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 (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 leads at a distance of 10 mm from case are kept at ambient temperature
( 3) Measured with device junction in thermal equilibrium and DC test conditions.
