JANS1N5312UR-1/TR

Current Regulation - Diodes, Transistors Overview

The JANS1N5312UR-1/TR is a current regulator diode manufactured by Microchip Technology, designed for space and high-reliability applications. It provides a regulated current of 4.73 mA with a maximum power dissipation of 500 mW and a peak operating voltage of 100 V. The device features a round-end surface-mount package in DO-213AB (MELF) configuration. It operates within a temperature range of -65°C to +175°C junction temperature. This component is qualified under JANS standards for enhanced radiation hardness and reliability.

Current Regulation - Diodes, Transistors Feature Summary

• JANS qualification for space-grade reliability and radiation tolerance
• Constant current regulation over a wide voltage range
• Surface-mount MELF package for compact integration

Current Regulation - Diodes, Transistors Applications

• Spacecraft electronic systems requiring radiation-hardened components
• High-reliability military avionics circuits
• Current limiting and regulation in harsh environment electronics

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific JANS radiation hardness assurance requirements against mission parameters. Confirm that the DO-213AB MELF package meets mechanical constraints. Ensure compatibility with RoHS exemptions if applicable for space flight hardware. Validate supplier authorization for JANS grade parts to guarantee traceability and lot history compliance.

Current Regulation - Diodes, Transistors Selection Notes

Select this part when a stable 4.73 mA current source is required in a surface-mount form factor. Compare against JAN or commercial variants if radiation hardness is not critical. Consider the 500 mW power rating and 100 V breakdown voltage for circuit design margins. Evaluate thermal management needs given the small MELF package size and high-temperature operation capability.

Current Regulation - Diodes, Transistors Part Context

This component belongs to the 1N53xx series of current regulator diodes produced by Microchip. The JANS suffix denotes a specific level of quality and testing for space applications, distinct from standard industrial or military grades. It shares functional similarities with other members of the series but offers specialized packaging and reliability attributes suitable for orbital deployment.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other JANS-qualified current regulators from Microchip such as JANS1N5311UR-1 or JANS1N5313UR-1, provided current ratings match. Cross-brand replacements require careful verification of radiation tolerance levels and package dimensions to ensure board compatibility.
