Overview
The SanRex DFA150AA80 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. The diode section supports a maximum repetitive peak reverse voltage of 800 V and an output current of 150 A at a case temperature of 93°C. The thyristor provides a peak on-state voltage of 1.35 V at 150 A and handles a surge on-state current of 1460 A. The module features an isolation breakdown voltage of 2500 V AC and operates within a junction temperature range of -40°C to +150°C.
Feature Summary
- Integrates a three-phase diode bridge and a DC-line thyristor into a single compact unit
- Provides electrical isolation between electrode terminals and the mounting base
- Allows multiple modules to be mounted together on the same heat sink fin
Applications
- Inverter systems for AC or DC motor control
- Current stabilized power supplies
- Switching power supplies
Procurement Notes
Verify the specific part number suffix against official documentation to confirm voltage ratings and technical specifications. Ensure that any ordering variations do not alter the functional characteristics unless explicitly stated by the manufacturer. Confirm thermal interface requirements and mounting torque specifications before integration.
Selection Notes
Select this module for applications requiring combined three-phase rectification and controlled DC output. Evaluate thermal resistance values based on the specific heatsink configuration and ambient conditions. Verify that the operating junction temperature remains within the specified limits during peak load scenarios.
Part Context
This component belongs to the DFA150AA series of complex isolated power modules manufactured by SanRex. The series includes variants such as the DFA150AA160, which shares similar structural and functional characteristics but differs in voltage ratings. These modules are engineered for robust performance in industrial power conversion environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative components from other manufacturers.
