Current Regulation - Diodes, Transistors Procurement Notes

Verify that the ordering suffix /TR indicates tape-and-reel packaging configuration. Confirm compliance with MIL-PRF-19500/463 requirements for military procurement. Ensure the DO-213AB package matches the design footprint. Validate the 473 µA current rating against specific circuit needs before finalizing orders.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a surface-mount current regulator with military qualification is required. Compare the 473 µA output against other variants like JAN1N5288UR-1 if different current levels are needed. Ensure the DO-213AB package fits the PCB layout constraints. Verify thermal management capabilities for the 500 mW dissipation rating in the target application.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the JAN1N528x series of current regulator diodes from Microchip. It shares the same DO-213AB package and general electrical characteristics as other members of the family, differing primarily in the regulated current value. The JAN prefix denotes military-grade qualification under specific performance standards.

Current Regulation - Diodes, Transistors Replacement Considerations

JAN1N5289UR-1 is a compatible alternative without reel packaging. Standard commercial versions like 1N5289/TR lack military qualification. Other series members such as JAN1N5288UR-1 offer similar packages but different current ratings.
