RS1JWF-HF

Single Diodes Overview

The RS1JWF-HF is a single fast recovery rectifier manufactured by Comchip Technology, designed for surface-mount applications in the SOD-123FL-2 package. It features a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current rating of 1 A. The device exhibits a forward voltage drop of 1.3 V at rated current and a low reverse leakage current of 5 uA. Key performance metrics include a maximum non-repetitive surge current of 30 A and a typical reverse recovery time of 250 ns. It operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Fast recovery characteristics optimized for high-frequency switching efficiency
• Plastic encapsulation utilizing molded compound meeting UL flammability standards
• Low thermal resistance construction supporting reliable operation in compact designs

Single Diodes Applications

• High-frequency power supply circuits
• Free-wheeling diode configurations in DC-DC converters
• Protection against voltage spikes in inductive load switching

Single Diodes Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official manufacturer documentation. Ensure storage conditions maintain integrity of the SMD/SMT package. Cross-reference datasheet revisions to validate electrical parameter consistency before integration into production designs.

Single Diodes Selection Notes

Select this component when a 600 V blocking capability and 1 A continuous current are required in a small form factor. The 250 ns recovery time suits moderate-speed switching applications. Compare with ES1JWF-HF if faster super-fast recovery is needed, or US1KWF-HF for higher voltage ratings. Evaluate thermal management requirements based on the specified operating temperature range.

Single Diodes Part Context

This part belongs to the Comchip Technology RS series of fast recovery rectifiers. It shares the SOD-123FL-2 footprint with other variants like RS2JWF-HF, which offers higher current capacity. The series targets general-purpose rectification where space constraints limit the use of larger packages like SMA or SMB.

Single Diodes Replacement Considerations

Direct substitutes include RS2JWF-HF for higher current needs. For faster recovery, consider ES1JWF-HF. Higher voltage options include US1KWF-HF. Verify pinout compatibility and thermal characteristics before substitution.
