Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 corresponds to the required tape-and-reel or bulk packaging configuration as defined by the manufacturer's official documentation. Confirm that the RoHS status marked as non-compliant aligns with project regulatory requirements. Ensure the supplier provides valid traceability certificates for the military grade designation.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable 825 µA reference current is required in space-constrained surface-mount designs. The DO-213AB package offers a compact footprint suitable for automated assembly. Consider the 100 V breakdown voltage limit when designing bias networks to ensure operation remains within safe electrical boundaries.

Current Regulation - Diodes, Transistors Part Context

This part is part of the 1N5294 family of current regulator diodes produced by Microchip/Microsemi. The JAN prefix indicates military grade quality, while TXV denotes specific screening levels. It shares the same functional profile as other variants in the series but differs in packaging and strictness of manufacturing controls.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JANTX1N5294UR-1 and JAN1N5294UR-1, which share identical electrical characteristics but may differ in screening levels or packaging options. Verify pinout compatibility and thermal performance before substitution.
