US1G-E3/61T

Single Diodes Overview

The US1G-E3/61T is a fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 400 V. The device utilizes a glass passivated chip junction for enhanced reliability. It is housed in the DO-214AC (SMA) surface-mount package, designed for automated placement. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 400 V and a typical reverse recovery time of 50 ns. The component operates within a junction temperature range of -55°C to 150°C.

Single Diodes Procurement Notes

Verify the specific suffix /61T corresponds to the tape and reel packaging configuration required for your assembly line. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the DO-214AC footprint matches your design specifications. Cross-reference the datasheet revision date to guarantee parameter accuracy during procurement.

Single Diodes Selection Notes

Select this component when a 400 V reverse voltage rating and 1 A continuous current are required in a compact SMA package. Consider the 50 ns reverse recovery time for efficiency in high-speed switching applications. Compare thermal resistance values against your heat dissipation requirements. Verify compatibility with existing board space constraints compared to through-hole alternatives.

Single Diodes Part Context

This part belongs to the US1 series of fast recovery rectifiers from Vishay. The E3 suffix indicates RoHS compliance and halogen-free construction. The /61T designation typically specifies the bulk or tape-and-reel packaging format. This series is engineered for general-purpose rectification where speed and reliability are critical factors in circuit design.

Single Diodes Replacement Considerations

Direct substitutes include other Vishay US1G variants with identical electrical ratings but different packaging options. Cross-brand equivalents must match the 400 V Vr, 1 A Io, and DO-214AC package dimensions. Verify reverse recovery time specifications to ensure functional parity in high-frequency designs.
