RS1KHM3_A/H

Single Diodes Overview

The RS1KHM3_A/H is a single standard recovery rectifier manufactured by Vishay Semiconductors. It features a glass passivation layer for enhanced stability and is housed in the DO-214AC (SMA) surface-mount package. The device supports a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 800 V. Key electrical characteristics include a forward voltage of 1.3 V, a reverse leakage current of 5 uA, and a typical reverse recovery time of 500 ns. It withstands a maximum surge current of 30 A and operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

• Glass passivated chip provides high reliability and stable performance under varying thermal conditions
• Utilizes plastic material rated UL Flammability Rating 94V-0 for safety compliance
• Designed for automated surface-mount assembly processes

Single Diodes Applications

• General purpose rectification in power supply circuits
• Freewheeling diodes in inductive load switching applications
• DC-DC converter output rectification

Single Diodes Procurement Notes

Verify the complete part number including suffixes such as /H or /I against official Vishay documentation to ensure correct packaging configuration. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Cross-reference the specific datasheet revision to validate electrical parameters before integration into design specifications.

Single Diodes Selection Notes

Select this component when an 800 V blocking capability is required in a compact SMA footprint. The 500 ns recovery time suits general-purpose applications rather than high-frequency switching. Ensure the circuit design accommodates the 1.3 V forward voltage drop and 5 uA leakage current at maximum operating temperatures.

Single Diodes Part Context

This device belongs to the RS1x series of glass passivated surface-mount rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent mechanical dimensions and electrical testing standards. The HM3 suffix indicates lead-free construction compliant with EU Directive 2002/95/EC on the restriction of hazardous substances.

Single Diodes Replacement Considerations

Direct replacements must match the 1 A current rating, 800 V reverse voltage, and DO-214AC package. Verify that substitute components exhibit comparable reverse recovery times and forward voltage characteristics to maintain circuit performance integrity.
