Bridge Rectifier Procurement Notes

Verify component authenticity through authorized IXYS distributors or certified suppliers. Request original manufacturer datasheets and compliance documentation prior to purchase. Confirm specific lot codes and manufacturing dates to ensure alignment with project timelines and quality standards.

Bridge Rectifier Selection Notes

Select this component when a 190 A continuous current rating and 1400 V blocking voltage are required. Ensure the application environment supports the specified operating temperature range. Verify that the mounting hardware accommodates the PWS-E package dimensions and thermal requirements for adequate heat sinking.

Bridge Rectifier Part Context

This part belongs to the VUO190 series of three-phase rectifiers from IXYS. The series offers various voltage ratings including 1600 V and 1800 V variants. The VUO190-14NO7 specifically addresses applications requiring 1400 V isolation while maintaining the high current handling capabilities characteristic of the 190 Amp family.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same series include the VUO190-16NO7 and VUO190-18NO7. These alternatives share identical current ratings and package styles but differ in peak reverse voltage specifications. Ensure the system voltage does not exceed the substitute's rating.
