| 1N4728 thru 1N4764 Zener Diodes PRODUCT SUMMARY VZ Range: 3.3 to 100 Volts Power Dissipation: 1.0 W 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 Zener voltages and tolerances are available upon request. These diodes are also available in the MELF case with type designation 1N4728 thru 1N4764 For bidirectional product, contact local Technical Sales office. Note: Suffix: "-P" to order Molded Plastic Package Suffix: "-G" to order Molded Glass Package MECHANICAL DATA Case: DO-41 Glass or DO-41 Plastic Case Weight: approx. 0.35g Pb-free; RoHS-compliant MAXIMUM RATINGS AND THERMAL CHARACTERISTICS (Ratings at 25 C ambient temperature unless otherwise specified.)

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 02/15/2008 Rev.1.00 www.SiliconStandard.com 2 1N4728 thru 1N4764 RATINGS AND CHARACTERISTIC CURVES (TA=25 C unless otherwise noted) o Information furnished by Silicon Standard Corporation is believed to be accurate and reliable.
