Overview
The SanRex DFA200CB80 is an isolated power module designed for rectification applications requiring rush current prevention. It integrates six diodes in a three-phase bridge configuration and one thyristor connected in series with the DC line. The device features a repetitive peak reverse voltage of 800 V, a maximum output current of 200 A at Tc=96°C, and a surge forward current of 1850 A. The thyristor section supports an average on-state current of 200 A at Tc=118°C with a peak on-state voltage of 1.15 V. Operating junction temperature ranges from -40°C to +150°C, and isolation breakdown voltage is 2500 Vrms.
Feature Summary
- Integrates a three-phase diode bridge and a series thyristor within a single isolated package
- Designed specifically for rectification circuits requiring inrush current suppression
- Provides high thermal performance with low junction-to-case thermal resistance
Applications
- Motor control inverters
- AC stabilized power supplies
- Switching mode power supplies (SMPS)
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number against official datasheets. Confirm technical specifications match application requirements, particularly regarding voltage ratings and thermal management constraints. Ensure proper mounting torque values are applied during installation to maintain electrical isolation and thermal integrity.
Selection Notes
Select this module when circuit designs require integrated inrush current limiting alongside three-phase rectification. Evaluate thermal impedance characteristics against heat sink capabilities to ensure junction temperatures remain within specified limits under continuous load conditions. Verify gate trigger parameters align with available control circuitry drive capabilities.
Part Context
This component belongs to the DFA series of isolated power modules manufactured by SanRex. The series combines diode and thyristor technologies to address specific industrial power conversion needs. Variants within the series differ primarily in voltage ratings while maintaining similar current handling and structural configurations.
Replacement Considerations
Direct replacements must match the 800V rating, 200A current capacity, and screw-mount packaging. Verify that substitute components offer equivalent isolation voltages and thermal characteristics to ensure compatibility with existing cooling systems and circuit protection mechanisms.
