Ensure handling procedures align with electrostatic discharge protection standards during installation.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required in a compact surface-mount footprint. The 473µA regulation point suits low-power signal conditioning tasks. Verify that the 100V breakdown rating exceeds the maximum circuit potential to prevent device failure under transient conditions.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the JAN1N5289 series of current regulator diodes produced by Microchip Technology. It shares functional characteristics with other members of the family but differs in regulatory current values and physical packaging configurations. The UR-1 suffix indicates a specific surface-mount variant distinct from through-hole equivalents.

Current Regulation - Diodes, Transistors Replacement Considerations

Parametric equivalents include JAN1N5289UR-1/TR for tape-and-reel packaging. Direct substitutes require matching the 473µA regulation current and 100V voltage rating. Verify package compatibility before substituting with similar current regulator diodes from other manufacturers.
