(Ratings at 25oC ambient temperature unless otherwise specified.)
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 Zener voltages and tolerances are
available upon request.
These diodes are also available in the MELF case with type
designation ZM4728 thru ZM4764
For bidirectional product, contact local Technical Sales office.
Case: DO-41 Glass or DO-41 Plastic Case
Weight: approx. 0.35g

(TA=25oC unless otherwise noted) Maximum VF=1.2V at IF=200mA
Notes: 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
(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 at a distance of 10 mm from case are kept at ambient temperature
3. Measured under thermal equilibrium and DC test conditions
