DFA150AA80

SCRs - Modules 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.

SCRs - Modules 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

SCRs - Modules Applications

• Inverter systems for AC or DC motor control
• Current stabilized power supplies
• Switching power supplies

SCRs - Modules 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.

SCRs - Modules 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.
