Overview
The SanRex DFA150AA160 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 operates within a junction temperature range of -40°C to +150°C for the diode section and up to +135°C for the thyristor. The module provides a repetitive peak reverse voltage of 1600V and an output current rating of 150A at a case temperature of 93°C. Key electrical parameters include a maximum forward voltage drop of 1.35V for the diodes and a peak on-state voltage of 1.35V for the thyristor. The unit weighs approximately 460g.
Feature Summary
- Integrates a three-phase diode bridge and a DC-line thyristor into a single compact module.
- Provides electrical isolation between electrode terminals and the mounting base.
- Designed for efficient thermal management allowing multiple modules to share the same heatsink fin.
Applications
- Inverter systems for AC or DC motor control
- Current stabilized power supplies
- Switching power supplies
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number DFA150AA160 with official SanRex documentation. Confirm that the specific ordering suffix corresponds to the 1600V rating rather than the 800V variant. Ensure procurement channels provide valid UL certification records (E76102) and technical datasheets to validate performance specifications before integration.
Selection Notes
Select this module when a combined three-phase rectification and controlled DC output is required in a single package. The 1600V rating suits higher voltage AC input applications compared to the 800V variant. Consider the 460g mass and M5/M6 screw mounting requirements for mechanical design. Verify that the system can maintain the case temperature at 93°C to achieve the rated 150A continuous current capacity.
Part Context
This component belongs to the DFA series of three-phase diode and thyristor hybrid modules from SanRex. It shares the same physical footprint and internal architecture as the DFA150AA80, differing primarily in the voltage blocking capability. The series is engineered for industrial power conversion where space efficiency and thermal isolation are critical design constraints.
Replacement Considerations
The DFA150AA80 serves as a lower-voltage alternative within the same series, offering identical current ratings but with an 800V reverse voltage capability. Substitution requires verifying that the circuit voltage does not exceed 800V. No other direct cross-model replacements are documented in the provided source material.
