Current Regulation - Diodes, Transistors Procurement Notes

Verify that the specific ordering suffix matches the required packaging configuration, as variations exist between bulk and tape-and-reel formats. Confirm compliance with MIL-PRF-19500/463 standards for intended defense or aerospace deployments. Ensure the supplier provides valid traceability documentation consistent with military-grade component sourcing requirements.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a surface-mount current regulator with high-temperature capability is required. Compare the 429 µA current rating against circuit load requirements. Consider the DO-213AB package dimensions for PCB layout constraints. Verify that the 100 V peak voltage rating exceeds the maximum expected reverse voltage in the application.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the JAN1N5288 series of current regulator diodes produced under the Microsemi/Microchip brand. It shares functional similarities with other devices in the MIL-PRF-19500/463 family but differs in specific current ratings and package types. The UR-1 suffix typically denotes the surface-mount MELF variant compared to through-hole equivalents.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JAN1N5288UR-1 from other authorized manufacturers if available. Cross-reference with JANTX1N5288UR-1 for higher reliability grades. Verify pinout compatibility and thermal performance before substituting in existing designs.
