SE12DGHM3/I

Single Diodes Overview

The SE12DGHM3/I is a standard recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage of 400 V and a maximum continuous forward current of 12 A. The device utilizes a surface-mount TO-263AC (SMPD) package with three pins. Key electrical characteristics include a peak non-repetitive forward surge current of 165 A, a maximum forward voltage of 1 V, and a peak reverse recovery time of 300 ns. The component supports an operating junction temperature range from -55°C to +175°C and holds AEC-Q101 automotive qualification.

Single Diodes Feature Summary

• Automotive-grade reliability certified under the AEC-Q101 standard for robust performance in demanding environments.
• High thermal stability enabling operation at junction temperatures up to 175°C.
• Surface-mount construction in a compact TO-263AC package designed for efficient PCB integration.

Single Diodes Applications

• Automotive power supply circuits requiring AEC-Q101 compliance
• General-purpose rectification in industrial electronics
• DC-DC converter output stages

Single Diodes Procurement Notes

Verify the specific suffix /I against official Vishay documentation to confirm package variant and tape-and-reel specifications. Ensure the procurement order explicitly references the full part number SE12DGHM3/I to distinguish it from other series members within the SE12D family. Cross-reference datasheet revision dates to guarantee alignment with current manufacturing standards and pinout configurations.

Single Diodes Selection Notes

Select this component when a 400 V rating and 12 A continuous current capacity are required in a surface-mount form factor. The 300 ns reverse recovery time makes it suitable for general-purpose applications rather than high-frequency switching. Consider the TO-263AC package dimensions for thermal management and board space constraints compared to through-hole alternatives.

Single Diodes Part Context

This device belongs to the SE12D series of standard recovery rectifiers from Vishay. The series offers various voltage ratings and packaging options tailored for different power levels. The SE12DGHM3/I specifically addresses the need for higher current handling in a slim profile package, bridging the gap between smaller signal diodes and larger through-hole power rectifiers.

Single Diodes Replacement Considerations

Consult official Vishay substitution guides for verified equivalents. Generic replacements must match the 400 V reverse voltage, 12 A forward current, and TO-263AC package footprint. Verify that any substitute also meets AEC-Q101 requirements if automotive application is intended.
