Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1/TR against the manufacturer's official datasheet to confirm the reel packaging format and exact electrical tolerances. Ensure the procurement channel provides traceability documentation required for MIL-PRF-19500/463 qualified parts. Cross-reference the manufacturer code to distinguish between original Microchip/Microsemi production and authorized distributors.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a surface-mount current regulator is required for space-constrained designs. The DO-213AB package offers a compact alternative to axial leads while maintaining hermeticity. Consider the 1 mA regulation value and 100 V breakdown capability to ensure compatibility with the target circuit's voltage and current requirements.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices offer standard 10% tolerance options ranging from 0.22 mA to 4.7 mA. The JAN1N5297UR-1/TR specifically represents the surface-mount variant of the 1N5297-1, providing equivalent performance in a MELF form factor.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JANTX1N5297UR and JAN1N5297UR-1 from manufacturers such as Compensated Devices Inc, MACOM, and Aeroflex Metelics. Verify that replacement parts maintain the same MIL-PRF-19500/463 qualification level and DO-213AB package dimensions.
