US1A-M3/61T

Single Diodes Overview

The US1A-M3/61T is a standard rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 50 V and an average rectified forward current (Io) of 1 A. The device utilizes the DO-214AC (SMA) surface-mount package. Key electrical parameters include a maximum reverse leakage current of 10 µA at 50 V, a typical forward voltage of 1 V at 1 A, and a reverse recovery time (trr) of 50 ns. The junction capacitance is specified as 15 pF at 4 V and 1 MHz. The component operates within a junction temperature range of -55°C to 150°C.

Single Diodes Feature Summary

• Standard rectification technology optimized for general-purpose applications
• Surface-mount construction in the compact DO-214AC (SMA) package
• High thermal stability with a maximum junction temperature rating of 150°C

Single Diodes Applications

• General-purpose rectification in power supply circuits

• DC-to-DC converter stages requiring fast recovery characteristics

Single Diodes Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging configuration and compliance status. Ensure that the requested part number matches the exact electrical specifications required for the design. Cross-reference datasheet revisions to confirm material composition and manufacturing origin details prior to procurement.

Single Diodes Selection Notes

Select this component when a 50 V reverse voltage rating and 1 A continuous current capacity are required in a surface-mount format. The 50 ns reverse recovery time makes it suitable for higher frequency switching applications compared to slower standard diodes. Verify that the DO-214AC footprint aligns with the printed circuit board layout constraints.

Single Diodes Part Context

This part belongs to the US1 series of standard rectifiers from Vishay, which includes variants with different voltage ratings such as US1B, US1D, US1G, US1J, US1K, and US1M. All members of this family share the same 1 A current rating and DO-214AC package but differ in their peak inverse voltage capabilities. The M3 suffix indicates lead-free termination compliant with RoHS directives.

Single Diodes Replacement Considerations

Direct substitutes within the same Vishay family include US1B-M3/61T, US1D-M3/61T, US1G-M3/61T, US1J-M3/61T, US1K-M3/61T, and US1M-M3/61T. These alternatives offer identical current and package specifications but provide higher reverse voltage ratings ranging from 100 V to 1000 V.
