Single Diodes Procurement Notes

Verify the manufacturer origin carefully, as documentation sources indicate production by Motorola (NXP), Microsemi, or Microchip Technology. Confirm the specific datasheet version matches your design requirements regarding thermal characteristics and pinout compatibility. Ensure the press-fit termination style aligns with your PCB or chassis mounting infrastructure before finalizing procurement.

Single Diodes Selection Notes

Select this component when a 100 V, 25 A rectifier with press-fit termination is required. The DO-21 package offers distinct advantages over through-hole options for high-vibration environments. Consider the 1.7 V forward voltage drop for efficiency calculations and ensure the 300 A surge capability meets transient load requirements.

Single Diodes Part Context

This part belongs to the family of silicon power rectifiers designed for general-purpose applications. Historically associated with the S/R35PF series, it serves as a standard solution for medium-power rectification tasks. The component represents a transition in manufacturing lineage between legacy semiconductor providers and current technology holders.

Single Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-reference compatibility with other 25 A, 100 V press-fit diodes only after confirming identical package dimensions and thermal resistance values.
