JANS1N4619DUR-1/TR

Single Zener Diodes Overview

The JANS1N4619DUR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for surface mount applications. It features a 3 V nominal Zener voltage with a tight ±1% tolerance and operates at a maximum power dissipation of 500 mW. The device utilizes a DO-213AA (SMB) package and is constructed using silicon technology. It is qualified to the JANS standard, indicating suitability for space-grade environments. Key electrical characteristics include a test current of 250 uA and a maximum reverse leakage current of 400 nA.

Single Zener Diodes Feature Summary

• Space-grade qualification compliant with JANS standards for radiation-hardened reliability
• High precision voltage regulation with ±1% Zener voltage tolerance
• Surface mount construction in a compact DO-213AA package for automated assembly

Single Zener Diodes Applications

• Radiation-tolerant voltage reference circuits in satellite systems
• Over-voltage protection in aerospace power distribution networks
• Precision clamping applications in military avionics electronics

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape and reel packaging configuration if required for automated placement processes. Confirm JANS qualification status through official Microchip documentation to ensure compliance with space program requirements. Check for RoHS exemption status as indicated in related product data. Validate lot traceability and testing certificates for critical aerospace deployments.

Single Zener Diodes Selection Notes

Select this component when high-reliability space-grade performance is mandatory alongside precise voltage regulation. The ±1% tolerance makes it suitable for sensitive analog references where standard commercial parts lack sufficient accuracy. Ensure the DO-213AA footprint matches the PCB design constraints. Consider thermal management capabilities within the 500 mW dissipation limit during circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N4619 series of Zener diodes produced under Microchip's ruggedized product lines. The JANS designation signifies screening and testing according to MIL-PRF-19500 specifications for space applications. It serves as a specialized variant of the standard 1N4619, offering enhanced reliability and radiation hardness compared to commercial equivalents.

Single Zener Diodes Replacement Considerations

JANS1N4619DUR-1 is the base equivalent without reel packaging. Standard commercial 1N4619 variants lack JANS qualification and radiation hardness. No direct pin-compatible space-grade substitutes are confirmed in public data.
