Single Diodes Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical ratings and mechanical dimensions. Ensure compatibility with existing thermal management solutions due to the stud mount design. Cross-reference part numbers carefully as variations may exist across different manufacturers or production batches.

Single Diodes Selection Notes

Select this component when a silicon rectifier with a 150 V reverse voltage rating and 40 A average current capacity is required. The DO-4 stud mount package necessitates appropriate heatsinking infrastructure. Confirm that the standard recovery characteristics align with the switching frequency requirements of the target application circuit.

Single Diodes Part Context

This part belongs to the broader family of silicon power rectifier diodes used in industrial and commercial power electronics. Similar parts often share the 1N118x series designation but vary in voltage and current ratings. The 1N1185R specifically addresses mid-range power requirements within this standardized classification system.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' versions of the 1N1185R specification. Verify pinout and thermal interface compatibility before replacing. Generic equivalents must match the 150 V reverse voltage and 40 A current ratings precisely.
