Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1/TR against the manufacturer's datasheet to confirm the MELF package and tape-and-reel packaging format. Ensure the JANTX radiation tolerance and temperature grade requirements align with the target system specifications before finalizing procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a compact, surface-mount constant current source is required for low-current applications. Compare the 242 µA regulation value against circuit requirements and ensure the 100 V peak voltage rating exceeds the maximum expected reverse voltage across the device during operation.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. These devices serve as counterparts to Zener diodes, regulating current rather than voltage. The series offers various current options from 0.22 mA to 4.7 mA in standard 10% tolerances.

Current Regulation - Diodes, Transistors Replacement Considerations

Commercial equivalents include the 1N5283B or generic CRD components rated for 242 µA. For direct military-grade replacement, verify compatibility with JAN1N5283-1 or JANS1N5283-1 based on package and qualification requirements.
