VUB72-16NO1

Bridge Rectifier Overview

The IXYS VUB72-16NO1 is a three-phase rectifier bridge with an integrated brake chopper, designed for high-power industrial applications. It features input rectifier diodes (D1-D6) rated at 1600 V peak reverse voltage and 110 A average forward current. The module includes a chopper circuit comprising an IGBT transistor and a HiPerFRED free-wheeling diode, both rated at 1200 V. The IGBT offers a saturation voltage of 2.4 V at 25 A, while the chopper diode exhibits a forward voltage of 3.1 V at 25 A. The component utilizes a V1-A package with screw mounting terminals and an isolated DCB ceramic base plate.

Bridge Rectifier Feature Summary

• Integrates a three-phase mains rectifier bridge with a dedicated brake chopper circuit containing an IGBT and a fast recovery free-wheeling diode.
• Constructed with an isolated DCB ceramic base plate providing large creepage and strike distances for enhanced reliability.
• Features solder terminals compatible with PCB mounting alongside standard screw mounting options.

Bridge Rectifier Applications

• Drives with mains input
• DC link configurations
• Inverter or chopper feeding the machine
• Motor and generator/brake operation

Bridge Rectifier Procurement Notes

Verify the specific suffix NO1 to confirm the 1600 V rating variant, as the VUB72 series includes other voltage ratings such as 1200 V. Confirm that the component status is End-of-Life (EOL) prior to procurement planning. Ensure thermal interface material specifications match the required thermal resistance values for the intended heatsink application.

Bridge Rectifier Selection Notes

Select this module when a combined rectifier and brake chopper solution is required for three-phase systems. Verify that the 110 A bridge current rating and 1200 V chopper voltage ratings align with the system's peak operating conditions. Consider the 35 g weight and V1-A package dimensions for mechanical integration within the drive enclosure.

Bridge Rectifier Part Context

The VUB72 series represents IXYS' high-integration power modules combining rectification and braking capabilities. This specific part belongs to the VUB family, which utilizes HiPerFRED technology for the free-wheeling diodes to minimize switching losses. The module is designed to replace discrete component solutions in compact drive architectures.

Bridge Rectifier Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The datasheet indicates the product is phased out; alternative selection requires evaluating equivalent three-phase rectifier bridges with integrated choppers from current IXYS portfolios or other manufacturers.
