Overview
The SanRex DFA200AA160 is a complex isolated power module designed for high-current circuits, integrating six diodes in a three-phase bridge configuration with a thyristor connected to the direct current line. It features screw mounting and silicon technology. Key electrical parameters include a repetitive peak reverse voltage of 1600 V, an output current of 200 A, and a forward voltage drop of 1.35 V. The operating junction temperature ranges from -30°C to +150°C for the diode section. The module has a typical mass of 460 g and provides an isolation breakdown voltage of 2500 V AC.
Feature Summary
- Combines a three-phase diode bridge and a DC-line thyristor in one compact unit
- Electrically isolated between electrode terminals and the mounting base
- Designed for efficient heat dissipation allowing multiple modules on the same heatsink fin
Applications
- Inverter systems for AC or DC motor control
- Current stabilized power supplies
- Switching power supplies
Procurement Notes
Verify the specific suffix (80 vs 160) against the datasheet to confirm the voltage rating. Confirm mounting torque specifications for M5 and M6 terminals during installation. Check RoHS compliance status via manufacturer documentation before integration into regulated equipment designs.
Selection Notes
Select this module when a combined three-phase rectifier and controlled DC element is required in a single package. Ensure the thermal resistance and case temperature limits are within the design constraints. Verify that the 1600V rating matches the system's peak reverse voltage requirements.
Part Context
This component belongs to the DFA series of complex isolated modules manufactured by SanRex. These modules are engineered for industrial power electronics applications requiring high current handling and compact form factors. The series includes variants with different voltage ratings to suit various circuit topologies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires matching the integrated diode-thyristor topology and identical electrical ratings.
