SGL41-20HE3_A/H

Single Diodes Overview

The SGL41-20HE3_A/H is a surface-mount Schottky barrier rectifier manufactured by Vishay Semiconductors. It features a single diode configuration housed in the DO-213AB (MELF) package. The device supports a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current of 1 A. Key electrical characteristics include a low forward voltage drop of 500 mV at 1 A, a maximum reverse leakage current of 500 uA, and a peak surge current rating of 30 A. It operates within a junction temperature range of -55°C to +125°C.

Single Diodes Feature Summary

• Schottky technology ensures low power losses and high efficiency through minimal forward voltage drop.
• Guardring design provides overvoltage protection for enhanced reliability.
• MELF package construction is optimized for automated placement processes.
• High surge capability allows handling of transient current loads.

Single Diodes Applications

• Automated surface mount assembly lines
• Low voltage DC-DC converter circuits
• Power supply freewheeling applications

Single Diodes Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact packaging and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the DO-213AB MELF footprint dimensions with your PCB layout guidelines before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for applications requiring efficient rectification at low voltages where minimal forward voltage drop is critical. The 1 A current rating suits moderate power levels, while the 20 V reverse voltage limit defines its operational boundary. Consider the MELF package for robustness in automated environments compared to traditional axial leads.

Single Diodes Part Context

This part belongs to the SGL41 series of Vishay General Semiconductor's surface-mount Schottky rectifiers. The series utilizes silicon planar technology designed for high efficiency. The HE3 designation indicates lead-free termination materials compliant with environmental directives, distinguishing it from older non-compliant variants in the same family.

Single Diodes Replacement Considerations

Consult official Vishay substitution guides for verified equivalents. Generic replacements may differ in guardring protection or thermal characteristics. Verify that any substitute maintains the DO-213AB footprint and matches the 20 V / 1 A ratings without compromising the low forward voltage performance.
