Select this component when a fixed 1.43 mA current source is required in a surface mount configuration. The 100 V breakdown voltage allows operation across a wide dynamic range. Consider the JANS grade specifically for missions involving ionizing radiation exposure. Verify thermal management capabilities against the 475 mW dissipation limit in the final enclosure design.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5300 series of silicon current regulator diodes produced under MIL-PRF-19500/463. The JANS designation indicates a specific level of screening and testing for space and high-reliability applications. It shares the electrical characteristics of the commercial 1N5300 but differs significantly in manufacturing controls, material purity, and radiation hardness testing protocols defined by military standards.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JAN1N5300UR-1 and JANTXV1N5300UR-1 from Microchip, though these lack the full JANS radiation hardness qualification. Cross-brand replacements require verification of MIL-PRF-19500/463 compliance and identical DO-213AB package dimensions to ensure mechanical fit.
