AS1FDHM3/H

Overview

The AS1FDHM3/H is a single standard recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 1.5 A. The device utilizes the eSMP package (DO-219AB) for surface mount installation. Key electrical parameters include a maximum forward voltage of 1.25 V at 1.5 A, a maximum non-repetitive peak forward surge current of 30 A, and a maximum reverse leakage current of 1 µA at 600 V. The junction temperature range extends from -55°C to +175°C.

Feature Summary

• Utilizes eSMP surface-mount packaging for compact board space efficiency
• Designed with avalanche-rated capability for robust operation
• Complies with AEC-Q101 automotive qualification standards

Applications

• Automotive electronics requiring high reliability
• General-purpose rectification in power supplies
• DC-DC converter circuits

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm exact electrical tolerances and marking codes. Ensure the ordering part number matches the required package variant and compliance certifications. Cross-reference the component with official Vishay documentation to validate availability status and lead times prior to procurement.

Selection Notes

Select this component for applications requiring a 600 V blocking voltage and 1.5 A continuous current in a small footprint. The eSMP package offers a compact alternative to larger through-hole or standard SMD diodes. Consider the avalanche rating if inductive load switching is present within the circuit design.

Part Context

This component belongs to the AS1F series of standard recovery rectifiers from Vishay. The series provides various voltage ratings within the same eSMP package family, allowing designers to maintain consistent mechanical footprints across different voltage requirements while leveraging the benefits of surface-mount technology.

Replacement Considerations

Consult the Vishay AS1F series datasheet for direct pin-compatible substitutes with matching voltage and current ratings. Verify that any replacement maintains the eSMP package dimensions and thermal characteristics.
