Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure the procurement channel provides traceability to the MIL-PRF-19500/463 standard. Confirm that the received components match the DO-213AB MELF glass package dimensions and lead finish requirements specified in the datasheet.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a surface-mount current regulator with military qualification is required. Compare the 748 µA nominal current against circuit needs. Consider the 475 mW power dissipation limit and the -55 °C to +175 °C operating range. Verify compatibility with the DO-213AB footprint during PCB layout design.

Current Regulation - Diodes, Transistors Part Context

This part is part of the 1N5293 series of current regulator diodes produced by Microchip. It shares the basic 1N5293 designation but includes specific military and surface-mount modifications indicated by the JANTX prefix and UR-1 suffix. It differs from through-hole variants like the JANTXV1N5293-1 by its package type and mounting style.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JAN1N5293UR-1 or JANTXV1N5293UR-1 if higher reliability grades are acceptable. Cross-reference with other manufacturers' MIL-PRF-19500/463 qualified MELF current regulators ensuring identical 748 µA current and 100 V voltage ratings.
