Note:
1. The Zener impedance is derived from the 1KHZ 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 electrodes at a distance of 10mm from case are kept at ambient temperature
3. Measured under thermal equilibrium and DC test conditions
