US1A R3G

Single Diodes Overview

The US1A R3G is a surface-mount switching diode from the US1X series, manufactured by Taiwan Semiconductor Corporation. It features a DO-214AC (SMA) package with two pins. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 50 V and a maximum continuous forward current (If) of 1 A. The device exhibits a peak reverse recovery time (trr) of 50 ns and a peak non-repetitive forward surge current (Ifsm) of 30 A. Additional specifications consist of a peak reverse current (Ir) of 5 µA, a maximum forward voltage (Vf) of 1 V, and an operating temperature range from -55°C to 150°C.

Single Diodes Feature Summary

• High-efficiency fast recovery rectifier design for low-loss switching applications
• Plastic encapsulation utilizing molded epoxy compliant with UL 94 V-0 flammability ratings
• Mechanical robustness designed to withstand high thermal shock during soldering processes

Single Diodes Applications

• General-purpose rectification in AC/DC power supply circuits
• Protection against reverse polarity in DC input lines
• Freewheeling diodes in inductive load switching environments

Single Diodes Procurement Notes

Verify the specific suffix 'R3G' against the manufacturer's official datasheet to confirm packaging configuration and compliance status. Ensure the component matches the required voltage and current ratings for the target circuit. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Single Diodes Selection Notes

Select this component when a 50 V reverse voltage rating and 1 A continuous current capacity are sufficient for the application. The 50 ns recovery time makes it suitable for general-purpose switching rather than high-frequency RF applications. Consider the DO-214AC footprint constraints and thermal management requirements for the final assembly design.

Single Diodes Part Context

This component belongs to the US1X series of surface-mount switching diodes produced by Taiwan Semiconductor. The series offers various voltage ratings ranging from 50 V to 1000 V within the same SMA package form factor. The US1A variant specifically targets low-voltage applications requiring efficient rectification and reliable performance in compact electronic designs.

Single Diodes Replacement Considerations

The Vishay Semiconductors US1A-M3/5AT serves as a verified alternative. Both parts share identical 50 V, 1 A specifications and utilize the DO-214AC package. Verify pinout compatibility and thermal characteristics before substituting.
