Single Diodes Procurement Notes

Verify the specific manufacturing lot date code against project requirements, as this component follows a make-to-order production model. Confirm compliance with REACH regulations, noting that the part does not meet RoHS standards. Ensure the ordering documentation explicitly references the base part number 1N1348 to avoid confusion with similar series variants. Validate that the DO-4 package dimensions match the designated PCB or chassis mounting holes prior to final procurement authorization.

Single Diodes Selection Notes

Select this component when circuit designs demand a 16 A continuous current capacity combined with a 600 V blocking voltage. The wide operating temperature range makes it suitable for harsh industrial environments where ambient heat is significant. Consider the axial leaded form factor if through-hole mounting or direct chassis attachment is required rather than surface mount alternatives.

Single Diodes Part Context

The 1N1348 belongs to the S/R20 series of rectifiers manufactured by Microchip Technology. This series is characterized by robust silicon planar die construction designed for high surge current capability. The component serves as a fundamental building block in discrete semiconductor applications, providing reliable unidirectional current flow for AC-to-DC conversion processes in heavy-duty electrical systems.

Single Diodes Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers before substitution. Ensure any alternative device matches the 16 A current rating, 600 V reverse voltage, and DO-4 package outline to maintain mechanical and electrical compatibility.
