S1KHM3_A/H

Single Diodes Overview

The S1KHM3_A/H is a glass passivated single rectifier from Vishay Semiconductors, housed in the DO-214AC (SMA) surface-mount package. It features an 800 V repetitive peak reverse voltage and a 1 A average forward rectified current capability. The device exhibits a maximum forward voltage of 1.3 V at rated current and a low leakage current of 5 uA. Designed for fast recovery applications with a 500 ns reverse recovery time, it withstands surge currents up to 30 A. Operating temperatures range from -55 C to +150 C junction temperature.

Single Diodes Feature Summary

• Glass passivation provides mechanical strength and protection against soldering tool errors
• Fast recovery characteristics suitable for high-frequency switching applications
• Low forward voltage drop contributes to improved system efficiency
• High thermal performance supports operation at elevated junction temperatures

Single Diodes Procurement Notes

Verify the complete part number including suffixes such as /H or /85A to ensure correct packaging configuration. Confirm RoHS compliance status through official datasheets before integration. Check for specific automotive qualification requirements if deploying in regulated environments. Validate component authenticity via authorized distribution channels to prevent counterfeit risks.

Single Diodes Selection Notes

Select this component when an SMA packaged rectifier with 800 V blocking capability is required. Ensure the 1 A continuous current rating meets circuit demands. Consider the 500 ns recovery time for compatibility with switching frequencies. Verify that the operating temperature range aligns with environmental constraints.

Single Diodes Part Context

This device belongs to the RS1x/S1x series of glass passivated fast recovery rectifiers manufactured by Vishay. These components are designed for general-purpose use in compact surface-mount designs. The series offers a balance of voltage rating and current handling within standard SMA footprints.

Single Diodes Replacement Considerations

Cross-reference with RS1KHM3_A/H for identical electrical specifications and pinout compatibility. Verify package dimensions and marking codes match existing board layouts before substitution.
