US1G-M3/5AT

Single Diodes Overview

The US1G-M3/5AT is a standard rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified current of 1A and a maximum repetitive peak reverse voltage of 400V. The device utilizes a DO-214AC (SMA) surface-mount package. Key electrical parameters include a maximum forward voltage of 1V at 1A, a maximum reverse leakage current of 10µA at 400V, and an operating junction temperature range from -55°C to 150°C.

Single Diodes Feature Summary

• Standard recovery technology for general-purpose rectification
• Surface-mount construction in a compact DO-214AC (SMA) package
• High thermal stability with an extended operating junction temperature range

Single Diodes Applications

• General-purpose rectification in power supply circuits
• Reverse polarity protection in electronic systems
• DC output rectification in consumer electronics

Single Diodes Procurement Notes

Verify the specific suffix /5AT against official Vishay documentation to confirm reel packaging specifications. Ensure the component matches the required 400V reverse voltage rating for the target application. Cross-reference the manufacturer part number with authorized distributor databases to confirm RoHS compliance status and active production availability before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 1A current rating and 400V blocking capability are required in a surface-mount form factor. The standard recovery characteristics suit applications where switching speed is not critical. Compare the forward voltage drop and reverse leakage specifications against alternative SMA-packaged diodes to ensure compatibility with thermal management and efficiency requirements.

Single Diodes Part Context

This component belongs to the US1 series of surface-mount rectifiers produced by Vishay. The series offers various voltage ratings within the same DO-214AC footprint, allowing for design flexibility. The M3 suffix typically indicates lead-free and halogen-free construction compliant with modern environmental directives.

Single Diodes Replacement Considerations

Direct substitutes include other Vishay US1G variants such as US1G-E3/5AT or US1G-M3/61T, provided the packaging format aligns with assembly requirements. Other manufacturers offering SMA-packaged 1A 400V standard rectifiers may serve as alternatives if pinout and electrical parameters match exactly.
