NSR1030QMUTWG

Bridge Rectifier Overview

The NSR1030QMUTWG is a single-phase Schottky bridge rectifier manufactured by onsemi. It features a peak reverse voltage of 30 V and an average rectified current of 1 A. The forward voltage drop is specified at 600 mV when conducting 1 A, with a maximum reverse leakage current of 20 µA at 30 V. The device operates within a junction temperature range up to 125°C and is housed in a surface-mount 4-UDFN (3x3 mm) package with a bare pad.

Bridge Rectifier Feature Summary

• Schottky technology for low forward voltage drop and fast switching characteristics
• Compact 4-UDFN surface-mount package designed for space-constrained PCB layouts
• Single-phase full-wave rectification capability

Bridge Rectifier Applications

• DC-DC converter input rectification
• Power supply freewheeling diodes
• Low voltage rectification circuits

Bridge Rectifier Procurement Notes

This component is officially classified as End-of-Life (EOL) by the manufacturer. Production has ceased, and availability is restricted to remaining stock or secondary market sources. Verification of authenticity and storage history is critical due to the discontinued status. Designers should initiate replacement strategies immediately to ensure long-term supply chain stability.

Bridge Rectifier Selection Notes

Select this component only if the 30 V rating and 1 A current capacity align precisely with circuit requirements. The 4-UDFN package necessitates specific thermal management considerations due to the exposed pad design. Verify that the 600 mV forward voltage meets efficiency targets. Given the EOL status, alternative components with similar electrical specifications and compatible footprints should be evaluated for new designs.

Bridge Rectifier Part Context

The NSR1030QMUTWG belongs to the NSR1030 series of Schottky bridge rectifiers from onsemi. This series is engineered for low-voltage, high-efficiency rectification applications. The QMUTWG suffix denotes the specific tape-and-reel packaging and RoHS-compliant material composition. It serves as a compact solution for replacing larger through-hole bridge rectifiers in modern surface-mount assembly processes.

Bridge Rectifier Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, engineers must identify equivalent components based on matching electrical parameters (30 V, 1 A, Schottky) and mechanical footprint compatibility.
