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.
