Current Regulation - Diodes, Transistors Procurement Notes

Verify that the specific ordering suffix matches the required military qualification level and packaging format. Confirm RoHS status as non-compliant for this specific part number. Ensure compatibility with existing surface-mount assembly processes given the MELF package type. Check for any recent PCN updates regarding assembly sites or labeling changes before finalizing procurement orders.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a surface-mount current regulator is required for high-reliability applications. Compare against axial-leaded equivalents if board space permits, noting the different thermal and mechanical properties. Ensure the operating voltage remains below the 100 V maximum limit. Verify that the 4.73 mA regulation current aligns with the target circuit design requirements.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5313 series of current regulator diodes, which are available in both through-hole and surface-mount configurations. The JANTX designation indicates a specific military grade within the broader family that includes JAN, JANS, and commercial variants. These devices serve as counterparts to Zener diodes by regulating current rather than voltage.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other JANTX1N5313 variants with compatible suffixes. Surface-mount alternatives may require verification of pinout and thermal resistance. Axial-leaded versions like 1N5313 offer electrical equivalence but differ in mounting style.
