Overview
The SanRex DCA200UA65 is a soft recovery diode module with a 650V repetitive peak reverse voltage rating and a 200A DC output current capacity at Tc=85°C. It features a typical forward voltage drop of 1.4V and a maximum reverse recovery time of 360ns. The unit utilizes screw mounting (M6) and operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a surge forward current of 1350A, an isolation voltage of 2500V AC, and a thermal resistance from junction to case of 0.19°C/W.
Feature Summary
- Balances low conduction loss with high softness characteristics via ion irradiation lifetime control.
- Reduces noise generation caused by high surge voltages during reverse recovery operations.
- Features a 40% reduction in thermal resistance through high heat radiation materials and internal design optimization.
Applications
- Plasma cutting machines
- Welding machines
- Power supplies
- PV inverters (Booster chopper circuit)
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm ratings and pinout compatibility before integration. Ensure that thermal management solutions meet the specified junction-to-case thermal resistance requirements for reliable operation under load conditions.
Selection Notes
Select this component for applications requiring high current handling with controlled reverse recovery behavior. Consider the 650V blocking capability and 200A continuous current rating when designing circuits for industrial power conversion or renewable energy systems where low switching noise is critical.
Part Context
This module belongs to the DCA series of discrete semiconductor diodes manufactured by SanRex Corporation. It is designed as a robust power electronic component suitable for demanding industrial environments, offering isolated packaging and high reliability for rectification duties.
Replacement Considerations
Consult official SanRex documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' modules without validating electrical and mechanical specifications against the original datasheet.
FAQ
What technology is used to achieve soft recovery characteristics?
The module uses local lifetime control via ion irradiation technology to balance low forward voltage loss with high softness.
What is the recommended mounting torque for the M6 terminals?
The recommended mounting torque value is between 2.5 and 3.9 N·m (25-40 kgf·cm).
How does the thermal resistance compare to previous designs?
Thermal resistance is reduced by approximately 40% due to the adoption of high heat radiation materials and a new internal configuration.
