VUO16-08NO1

Bridge Rectifier Overview

The VUO16-08NO1 is a three-phase rectifier bridge manufactured by IXYS, designed for high-reliability power conversion applications. It features a DCB ceramic base plate and planar passivated chips to ensure robust performance under thermal stress. The module provides a maximum repetitive peak reverse voltage (VRRM) of 800 V and supports an average forward current (IdAV) of 20 A at a case temperature of 90°C. Key electrical parameters include a peak non-repetitive forward surge current (IFSM) of 106 A for 8.3 ms pulses, a typical forward voltage drop (VF) of 1.15 V at 7 A, and a maximum reverse leakage current of 0.3 mA at 25°C. The device operates within a junction temperature range of -40°C to +130°C and offers an isolation voltage of 3600 Vrms.

Bridge Rectifier Feature Summary

• Utilizes DCB ceramic base plate construction for enhanced thermal management and mechanical stability.
• Incorporates planar passivated silicon chips to improve resistance to environmental factors and thermal cycling.
• Provides high isolation voltage capability suitable for demanding industrial environments.

Bridge Rectifier Applications

• Input rectifiers for PWM inverters

• Battery DC power supplies
• Field supply for DC motors

Bridge Rectifier Procurement Notes

Verify the specific voltage rating suffix in the part number against the required system blocking voltage. Confirm that the mounting torque specifications for the M5 or 10-32 UNF terminals are strictly adhered to during installation to maintain the rated isolation voltage and thermal performance. Ensure the heat sink interface meets the specified thermal resistance requirements for the intended operating current.

Bridge Rectifier Selection Notes

Select this component when a compact three-phase rectification solution with high surge current capability is required. The 20 A average current rating at 90°C case temperature makes it suitable for moderate power density designs. Consider the 1.15 V forward voltage drop for efficiency calculations and verify that the 3600 V isolation rating exceeds the system's safety insulation requirements.

Bridge Rectifier Part Context

This component belongs to the VUO16 series of three-phase rectifier bridges from IXYS. The series includes variants with different voltage ratings, such as the VUO16-12NO1 (1200 V), VUO16-14NO1 (1400 V), VUO16-16NO1 (1600 V), and VUO16-18NO1 (1800 V). All variants share the same physical package dimensions and thermal characteristics, differing primarily in their blocking voltage capabilities.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 20 A current rating, 800 V blocking voltage, and V1-A-Pack style housing. Verify that substitute modules offer comparable thermal resistance (RthJH) and isolation voltage ratings to ensure system reliability without redesigning the cooling infrastructure.
