DMA90U1800LB-TRR

Bridge Rectifier Overview

The DMA90U1800LB-TRR is a three-phase bridge rectifier manufactured by IXYS, designed for high-power AC to DC conversion. It features a maximum repetitive peak forward current of 90 A and a maximum off-state voltage of 1.8 kV. The device utilizes the ISOPLUS-SMPD surface-mount package, supporting a maximum operating temperature of 175°C. Key electrical characteristics include a non-repetitive peak forward current of 380 A and a typical forward voltage drop of 1.4 V at rated conditions.

Bridge Rectifier Feature Summary

• Three-phase rectification capability for industrial power systems
• Surface-mount ISOPLUS-SMPD package design
• High thermal stability with 175°C operating limit

Bridge Rectifier Applications

• Industrial motor drives
• Uninterruptible power supplies (UPS)
• Welding equipment

Bridge Rectifier Procurement Notes

Verify that the suffix TRR corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm the exact datasheet revision matches the intended electrical specifications. Ensure the supplier provides traceability documentation consistent with IXYS manufacturing standards. Cross-reference the part number against official distributor catalogs to avoid substitution errors.

Bridge Rectifier Selection Notes

Select this component when high-voltage three-phase rectification is required in space-constrained designs. The surface-mount format facilitates automated PCB assembly compared to through-hole alternatives. Evaluate thermal management requirements based on the 175°C junction temperature rating. Consider the 1.8 kV blocking voltage for compatibility with standard industrial AC line voltages.

Bridge Rectifier Part Context

This part belongs to the IXYS ISOPLUS-SMPD series of surface-mount power devices. It serves as a compact alternative to traditional bolt-down or through-hole bridge rectifiers. The series emphasizes improved thermal performance and reduced footprint for modern power electronics applications requiring robust three-phase conversion.

Bridge Rectifier Replacement Considerations

Direct substitutes include the DMA90U1800LB-TUB variant, which shares identical electrical specifications but differs in packaging format. Verify mechanical mounting dimensions and pinout compatibility before implementation.
