1) The Zener Impedance is derived from the 60 Hz 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)
3)
Measured under thermal equilibrium and DC test conditions.
Tested with pulses tp = 20 ms.
