Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix to confirm the exact variant and compliance status. Confirm that the DO-213AB-2 package matches the target footprint. Ensure the manufacturer source is authorized to guarantee authenticity for military-grade components. Check for any specific handling requirements associated with hermetic glass packages during assembly.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed 825 µA current source is required in a surface-mount configuration. The 100 V breakdown voltage allows for significant headroom in series applications. Consider the thermal constraints imposed by the 475 mW power rating. Verify compatibility with the target operating temperature range defined by the military specification.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the JAN1N5294 family of current regulator diodes produced under MIL-PRF-19500/463 standards. It shares the functional characteristics of the standard 1N5294 but meets stricter military qualification criteria. The UR-1 suffix denotes the specific surface-mount MELF package variant offered by Microchip.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JANTX1N5294UR-1 and JANTXV1N5294UR-1 from the same manufacturer family. These variants share the DO-213AB package and core electrical functions while differing in quality screening levels.
