VUO52-18NO1

Bridge Rectifier Overview

The IXYS VUO52-18NO1 is a three-phase bridge rectifier module from the VUO52 series, designed for high-power industrial applications. It features a peak repetitive reverse voltage (Vrrm) of 1800 V and an average forward current (Io) of 54 A. The device exhibits a typical forward voltage drop of 1.13 V at 20 A and a maximum non-repetitive peak surge current (Ifsm) capability. Operating within a junction temperature range of -40°C to +150°C, it utilizes a screw-mount installation style in a V1-A-Pack package with five pins. The module ensures reliable performance with a low reverse leakage current of 40 µA at rated voltage.

Bridge Rectifier Feature Summary

• Three-phase bridge configuration for efficient AC-to-DC conversion
• High thermal stability supporting operation up to 150°C junction temperature
• Robust mechanical design with screw-mount compatibility for secure panel installation
• Low forward voltage drop characteristics for improved energy efficiency

Bridge Rectifier Applications

• Industrial motor drives and variable frequency drives
• Uninterruptible power supply (UPS) systems
• Welding equipment power stages
• General industrial power conversion units

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix NO1 against the manufacturer's latest datasheet to confirm pinout and terminal configuration. Ensure that the required thermal interface material and mounting hardware are compatible with the V1-A-Pack housing dimensions. Cross-reference the part number with authorized distributors to confirm current production status and availability before finalizing procurement plans.

Bridge Rectifier Selection Notes

Select this component when a 1800 V rating and approximately 54 A continuous current capacity are required for three-phase rectification. Consider the 1.13 V forward voltage drop for thermal management calculations. Verify that the application environment supports the specified operating temperature range and that the screw-mount package fits the available chassis space.

Bridge Rectifier Part Context

This module belongs to the IXYS VUO52 series, which provides standardized three-phase rectification solutions. The series is characterized by robust silicon technology and durable packaging suitable for demanding industrial environments. The VUO52-18NO1 variant specifically addresses higher voltage requirements compared to lower-rated siblings in the same family.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 1800 V reverse voltage, 54 A current rating, and V1-A-Pack package outline. Verify electrical parameters such as forward voltage and leakage current to ensure equivalent performance. Consult the manufacturer's cross-reference guide for approved alternative part numbers.
