Bridge Rectifier Procurement Notes

Verify component authenticity by cross-referencing the Data Matrix barcode on the module label against Infineon's official database. Ensure the serial number and material number match the provided documentation. Confirm compliance with IEC standards required for your specific industrial application environment before finalizing procurement.

Bridge Rectifier Selection Notes

Select this module when a compact, high-efficiency single-phase rectifier solution is required for EV charging infrastructure. The 1200 V rating and 40 A continuous current capability suit medium-power DC-AC or AC-DC topologies. Verify that the system can accommodate the PressFIT mounting method and utilize the integrated NTC for thermal protection strategies.

Bridge Rectifier Part Context

This component belongs to the DDB2U series within Infineon's EasyBRIDGE portfolio. It represents a specialized silicon carbide (SiC) based rectifier designed to replace traditional silicon diodes in high-frequency applications. The module integrates thermal sensing directly into the power semiconductor package to enhance system reliability.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 1200 V / 40 A rating and EasyBRIDGE form factor. Consider variants like DDB2U60N12W1RF_B11 for higher current requirements or DDB2U20N12W1RF_B11 for lower current needs, ensuring identical mounting and electrical interface compatibility.
