VUO82-12NO7

Overview

The IXYS VUO82-12NO7 is a three-phase rectifier bridge module from the VUO82 series, designed for high-power applications. It features a maximum repetitive reverse voltage (VRRM) of 1200 V and an average forward current (IdAV) of 88 A at a case temperature of 110°C. The device has a peak non-repetitive surge current (IFSM) rating of 820 A under sine wave conditions at 60 Hz for 8.3 ms. It utilizes planar passivated chips within a screw-terminal package, offering an isolation voltage of 3000 Vrms. The module operates within a junction temperature range of -40°C to +150°C and weighs approximately 160 g.

Feature Summary

• Planar passivated chip technology for robust blocking performance
• Integrated isolation voltage capability up to 3000 Vrms
• Screw terminal mounting design for secure mechanical connection

Applications

• Input rectifiers for PWM inverters
• Supplies for DC power equipment

• Field supply for DC motors

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm voltage and current ratings. Ensure compatibility with existing thermal management systems, as the module requires appropriate heat sinking to maintain the specified operating temperatures. Confirm that the mounting torque specifications are strictly followed during installation to prevent mechanical failure or electrical contact issues.

Selection Notes

Select this component when a three-phase rectification solution with 1200 V blocking capability and 88 A continuous current is required. Consider the thermal resistance values provided in the datasheet for accurate heat sink sizing. Evaluate the physical dimensions and mounting hole patterns to ensure fitment within the target enclosure. Compare the surge current ratings against potential fault conditions in the application circuit.

Part Context

This part belongs to the IXYS VUO82 series of three-phase rectifier bridges. The series offers various voltage ratings ranging from 600 V to 1800 V, sharing similar packaging and mounting characteristics. The VUO82 designation indicates an 88 A current class, distinguishing it from the lower-current VUO62 series. These modules are engineered for industrial power conversion environments requiring reliable high-current handling.

Replacement Considerations

Cross-reference with other VUO82 series variants such as VUO82-06NO7, VUO82-08NO7, VUO82-14NO7, or VUO82-16NO7 if different voltage ratings are needed while maintaining the same current capacity and package type.
