JANS1N4619DUR-1

Single Zener Diodes Overview

The JANS1N4619DUR-1 is a single Zener diode manufactured by Microchip Technology, designed for surface mount applications in the DO-213AA package. It features a nominal Zener voltage of 3 V with a tight tolerance of ±1%. The device supports a power dissipation of 500 mW and operates within a temperature range suitable for harsh environments. This component is part of the HRDS (High Reliability Diode Series) product line, indicating its qualification for demanding operational conditions.

Single Zener Diodes Feature Summary

• Surface mount construction utilizing the DO-213AA package format
• High precision voltage regulation with ±1% tolerance
• Qualified for High Reliability Diode Series (HRDS) standards

Single Zener Diodes Applications

• Harsh environment electronic systems requiring high reliability
• Voltage reference circuits in aerospace or defense equipment
• Precision voltage regulation in surface mount assemblies

Single Zener Diodes Procurement Notes

Verify that the specific procurement order explicitly confirms the JANS radiation hardening qualification level, as standard commercial variants lack this specification. Ensure the supplier provides traceability documentation consistent with HRDS requirements. Confirm the package type matches the DO-213AA footprint to avoid integration errors during assembly.

Single Zener Diodes Selection Notes

Select this component when a 3 V reference with strict ±1% accuracy is required in a surface mount form factor. The JANS designation indicates suitability for radiation-hardened applications, distinguishing it from standard commercial Zener diodes. Consider the 500 mW power rating and thermal management needs within the DO-213AA package constraints for the target design.

Single Zener Diodes Part Context

This part belongs to Microchip's portfolio of voltage and current regulation devices, specifically under the HRDS category. It shares the base electrical characteristics of the 1N4619 series but is packaged for surface mount technology. The JANS suffix denotes specific military or space-grade processing and testing protocols applied to the standard diode structure.

Single Zener Diodes Replacement Considerations

The JANTX1N4619DUR-1 is a related surface mount variant within the same family. Verify if the specific JANS radiation hardness qualification is mandatory for the application, as non-JANS parts may not meet the same environmental resilience standards.
