DFA100BA160

SCRs - Modules Overview

The SanRex DFA100BA160 is a complex isolated power module designed for high-current circuits, integrating six diodes in a three-phase bridge configuration with a single thyristor connected to the direct current line. It features screw mounting and electrical isolation between electrode terminals and the mounting base. Key ratings include a repetitive peak reverse voltage of 1600 V, a maximum non-repetitive peak reverse voltage of 1700 V, and an output current of 100 A at a case temperature of 98°C. The forward voltage drop is 1.30 V, with a thermal impedance from junction to case of 0.20 °C/W. Operating temperatures range from -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 for safe parallel installation on shared heatsinks.
• Designed for robust performance in high-current circuit applications.

SCRs - Modules Applications

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

SCRs - Modules Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and datasheet specifications. Confirm technical compliance with system requirements, including voltage ratings, current capacity, and thermal characteristics. Ensure proper handling procedures are followed due to the sensitive semiconductor nature of the device.

SCRs - Modules Selection Notes

Select this module when a combined three-phase rectification and thyristor control function is required in a single package. Consider the 1600V rating and 100A current capacity against load demands. Verify that the mounting torque specifications (1.5-2.5 N·m) and thermal management solutions align with the application's mechanical and thermal constraints.

SCRs - Modules Part Context

This component belongs to the SanRex DFA series of three-phase diode/thyristor modules. It shares the same physical footprint and general design philosophy as the DFA100BA80, differing primarily in its higher voltage blocking capability. The series is characterized by compact, isolated designs intended for industrial power conversion.

SCRs - Modules Replacement Considerations

The DFA100BA80 is a related variant within the same series offering identical current ratings but a lower 800V voltage rating. Substitution requires verification that the system voltage does not exceed 800V. No other direct substitutes are confirmed in the provided documentation.
