1N4728A,113

Single Zener Diodes Overview

The Nexperia 1N4728A,113 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It features a nominal working voltage of 3.3 V with a tolerance of ±5%. The device has a maximum total power dissipation of 1000 mW and operates within a junction temperature range of -65 °C to +200 °C. Key electrical characteristics include a forward voltage of 1.2 V at 200 mA, a test current of 76 mA, a differential resistance of 10 Ω, and a reverse current of 400 μA at 1 V.

Single Zener Diodes Feature Summary

• Hermetically sealed small glass package for environmental protection
• Low voltage regulation capability within the specified series range
• Axial leaded configuration for through-hole mounting

Single Zener Diodes Applications

• Low voltage stabilizers

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required packaging format, as standard distribution may vary between cut tape and reel quantities. Confirm compliance with RoHS directives and REACH regulations prior to integration. Ensure the specific lot code aligns with current production status and longevity program commitments to avoid obsolescence risks during the design-in phase.

Single Zener Diodes Selection Notes

Select this component when a stable 3.3 V reference is required in a through-hole axial package. The SOD66 form factor supports high thermal reliability due to its hermetic seal. Consider the 1000 mW power dissipation limit and the specific test current requirements for accurate voltage regulation in the target circuit environment.

Single Zener Diodes Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series covers nominal working voltages from 3.3 V to 24 V. All devices in this family share the same hermetically sealed small SOD66 (DO-41) glass package construction and similar limiting values.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-41 packaged Zener diodes rated at 3.3 V. Verify that alternative parts meet the same hermetic sealing requirements and thermal resistance specifications to ensure equivalent performance in existing designs.
