NOTES:
(1) On FR-5 board using recommended solder pad layout.
(2) On alumina substrate.
(1) The Zener Impedance is derived from the 1kHZAC voltage which results when an AC current having an
RMS value equal to 10% of the Zener current (I
ZT
or IZK) is superimposed on IZTor IZK.
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 a pulse test current.
Ratings at 25°C ambient temperature unless otherwise specified.
