Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix UR-1/TR against the manufacturer's latest datasheet to confirm package type and tape-and-reel packaging details. Ensure the JANTXV qualification level matches the project's radiation and reliability requirements. Cross-reference the MIL-PRF-19500/463 compliance status directly with Microchip Technology documentation before procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current sink is required in a compact MELF package. Compare the 242 uA regulation point against circuit load requirements. Verify that the 100 V peak operating voltage exceeds the maximum potential difference across the device in the intended application. Consider thermal dissipation limits within the 0.5 W power rating.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of current regulator diodes. These devices serve as counterparts to Zener diodes, regulating current rather than voltage. The series offers various current values from 0.22 mA to 4.7 mA in standard 10% tolerances, providing designers with options for different current limiting needs in axial or MELF packages.

Current Regulation - Diodes, Transistors Replacement Considerations

Check for direct equivalents such as JAN1N5283UR-1 or commercial versions like 1N5283 if military qualification is not required. Verify pinout compatibility and electrical parameters including regulation current tolerance and impedance characteristics before substitution.
