VUO35-18NO7

Bridge Rectifier Overview

The VUO35-18NO7 is a three-phase bridge rectifier manufactured by IXYS, designed for high-power industrial applications. It features a peak repetitive reverse voltage of 1.8 kV and an average forward current rating of 35 A. The device utilizes screw mount installation within a PWS-E-5 package, measuring 94 mm in length, 54 mm in width, and 30 mm in height. Key electrical parameters include a maximum forward voltage drop of 1.2 V, a surge current capacity of 600 A, and a power dissipation rating of 100 W. The unit operates reliably within a temperature range of -40°C to +150°C.

Bridge Rectifier Procurement Notes

Verify the manufacturer part number against official IXYS documentation to ensure authenticity. Confirm that the specific suffix matches the required voltage and current ratings. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure proper handling procedures are followed due to the semiconductor sensitivity.

Bridge Rectifier Selection Notes

Select this component when a compact three-phase rectification solution is required for moderate current loads up to 35 A. The 1.8 kV blocking voltage makes it suitable for higher voltage AC input lines. Consider the PWS-E-5 package dimensions for PCB or chassis layout constraints. Evaluate thermal management requirements based on the 100 W power dissipation rating at the expected ambient temperature.

Bridge Rectifier Part Context

This component belongs to the VUO series of three-phase rectifier bridges from IXYS. The series is characterized by robust construction and high reliability for demanding power electronics environments. Similar models in the lineup vary primarily in current ratings and voltage thresholds while maintaining compatible mounting styles.

Bridge Rectifier Replacement Considerations

Cross-reference with other IXYS VUO series modules such as VUO35-16NO7 for lower voltage applications. Verify pinout compatibility and thermal resistance values before substituting with generic equivalents. Ensure any replacement meets the same 1.8 kV reverse voltage requirement.
