Single Diodes Procurement Notes

Verify RoHS compliance status prior to procurement, as this component is explicitly listed as non-compliant with RoHS directives. Confirm that the specific manufacturing site and packaging label changes documented in recent PCNs align with project requirements. Ensure the ordering suffix matches the exact physical package and terminal configuration required for the design.

Single Diodes Selection Notes

Select this component when high current handling and rugged mechanical mounting are required. The DO-4 package necessitates appropriate heatsinking infrastructure. Evaluate the standard recovery time against switching frequency requirements to ensure compatibility with the circuit topology. Verify that the 400 V reverse voltage rating provides sufficient margin for the peak inverse voltage in the target application.

Single Diodes Part Context

This part belongs to the Microchip S/R25 series of silicon rectifiers. These devices are engineered for durability in demanding environments. The 1N1204C variant specifically addresses the need for moderate voltage blocking capabilities combined with significant current carrying capacity in a mechanically secure package format.

Single Diodes Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the DO-4 stud mount form factor and meets or exceeds the 400 V / 25 A ratings.
