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
)
is superimposed on I
ZT
. 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 0.575" (9.52mm) from case are kept at ambient temperature.
(3) Measured with device junction in thermal equilibrium.
