Type Number
(Note 1)
Note: 1. Type numbers listed have standard tolerance on the nominal Zener voltage of ±5%.
2. Measured under thermal equilibrium and DC (
Izt
) test conditions.
3. The Zener impedance is derived from the 60Hz AC voltage which results when an AC current having an RMS value
equal to 10% of the Zener current (
Izt
or
Izk
) is superimposed on
Izt
or
Izk
. Zener impedance is measured at two points
to insure a sharp knee on the breakdown curve and to eliminate unstable units.
