Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific revision level and lot traceability documentation upon receipt. Confirm that the component meets the required MIL-PRF-19500/463 qualification standards for the intended application environment. Ensure proper handling procedures are followed due to the hermetic glass MELF packaging.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise 748 µA regulation current is required in a compact surface-mount form factor. Compare against other members of the 1N5283UR-1 through 1N5314UR-1 series if different current values or tolerance levels are needed. Ensure the DO-213AB footprint matches the design layout constraints.

Current Regulation - Diodes, Transistors Part Context

This part is part of the broader 1N5283UR-1 through 1N5314UR-1 series of 0.5-watt 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 10 mA in standard 10% tolerances, all housed in the same DO-213AB package.

Current Regulation - Diodes, Transistors Replacement Considerations

Compatible substitutes include other JANTX1N5293 variants from qualified manufacturers adhering to MIL-PRF-19500/463. Verify pinout compatibility and electrical parameter equivalence before substitution.
