SILICON PLANAR POWER ZENER DIODES
Silicon Planar Power Zener Diodes
for use in stabilizing and clipping circuits with high power
rating. Standard Zener voltage tolerance is 10%. Add
suffix îš“Aîš” for 5% tolerance. Other tolerances available
upon request.

Notes:
(1) The Zener Impedance is derived from the 60 Hz 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.
(2) Valid provided that leads at a distance of 8 mm from case are kept at ambient temperature.
(3) Measured under thermal equilibrium and DC test conditions.
