DF100LB80

Bridge Rectifier Overview

The SanRex DF100LB80 is a silicon-based discrete semiconductor module designed for three-phase full-wave rectification. It integrates six diodes in an isolated bridge configuration, providing an output current of 100 A at a case temperature of 90°C. The device supports repetitive peak reverse voltages up to 800 V with a maximum forward voltage of 1.3 V. It operates within a junction temperature range up to 150°C and features screw mount installation.

Bridge Rectifier Feature Summary

• Isolated mounting base allows for simplified heatsink construction without electrical insulation requirements between the module and the heat sink.
• Three-phase bridge topology integrates six elements for efficient AC-DC conversion in industrial power electronics.
• High thermal stability supports operation at elevated junction temperatures up to 150°C.

Bridge Rectifier Applications

• Three-phase AC-DC rectification in industrial power supplies
• Input rectification for motor control systems
• Industrial power conversion equipment

Bridge Rectifier Procurement Notes

Verify the specific suffix designation against official SanRex documentation to confirm voltage ratings and pinout compatibility. Confirm RoHS compliance status through the manufacturer's latest datasheet or component certification records before integration into regulated assemblies.

Bridge Rectifier Selection Notes

Select this module for applications requiring 100 A continuous current in a three-phase bridge arrangement. Ensure the system design accommodates the 1.3 V forward voltage drop and provides adequate thermal management to maintain the case temperature below 90°C during operation.

Bridge Rectifier Part Context

This component belongs to the SanRex DF series of power diode modules. The series includes variants with different voltage ratings, such as the DF100LA80 and DF100LB160, offering flexibility for various isolation and voltage requirements in power conversion circuits.

Bridge Rectifier Replacement Considerations

Cross-reference with other SanRex DF series modules like DF100LA80 for similar current ratings but verify exact voltage and pin configurations. No direct third-party substitutes are confirmed in public documentation; ensure mechanical and electrical parameters match exactly.
