ZM4734
ZM4728 THRU ZM4764
SILICON PLANAR POWER ZENER DIODES
Features
Silicon Planar Power Zener Diodes
for use in stabilizing and clipping circuits with high power
rating. Standard Zener voltage tolerance is 10%. Add
suffix “A” for 5% tolerance. Other tolerances available
upon request.
These diodes are also available in DO-41 case with the
type designation 1N4728 thru 1N4764.
These diodes are delivered taped.
Details see “Taping”.

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 electrodes are kept at ambient temperature.
(3) Measured under thermal equilibrium and DC test conditions.
