VUO98-12NO7

Overview

The IXYS VUO98-12NO7 is a three-phase bridge rectifier module from the VUO series, designed for high-power industrial applications. It features a peak repetitive reverse voltage (Vrrm) of 1200 V and an average forward current (Id) of 105 A at a case temperature of 115°C. The module utilizes PWS-E packaging with screw terminals for secure mounting. Key electrical parameters include a maximum surge current (Ifsm) of 750 A, a typical forward voltage drop (Vf) of 0.81 V, and a maximum reverse leakage current (Ir) of 3.5 mA. It operates within a junction temperature range up to 150°C.

Feature Summary

• Utilizes planar passivated chips with DCB technology for improved reliability and thermal performance.
• Features low forward voltage drop to enhance efficiency in power conversion systems.
• Provides 3000 Vrms isolation voltage with UL recognition for safety compliance.

Applications

• Industrial motor drives and variable frequency drives (VFDs).
• Uninterruptible power supply (UPS) systems.
• Welding equipment and high-current power supplies.

Procurement Notes

Verify the specific suffix NO7 against the manufacturer's latest datasheet to confirm terminal configuration and pinout compatibility. Ensure that the required thermal interface material and mounting torque specifications are available for the PWS-E package type before integration into the final assembly design.

Selection Notes

Select this component when a 1200 V rating is required for three-phase rectification with an average current capacity around 105 A. Compare the forward voltage drop and thermal resistance values against alternative packages like V1-A-Pack or ECO-PAC 2 if space constraints differ. Confirm that the system's cooling solution can maintain the case temperature within the specified limits for optimal current derating.

Part Context

This part belongs to the IXYS VUO series of three-phase rectifier bridges, which are engineered for robust performance in demanding power electronics environments. The series offers various current ratings and voltage classes, utilizing standardized packaging formats to facilitate easy replacement and integration into existing industrial power converter designs.

Replacement Considerations

Direct substitutes within the same series include the VUO98-16NO7 (1600 V rating) or VUO98-18NO7 (1800 V rating), provided the higher voltage ratings do not conflict with system design margins. Verify mechanical dimensions and terminal spacing match the existing PCB or busbar layout before substitution.
