Overview
The SCA200DA160 is a thyristor module manufactured by SanRex Corporation. It features a repetitive peak reverse voltage of 1600 V and an average on-state current rating of 200 A at Tc=82°C. The surge on-state current capacity is 6000 A for a half-cycle at 50/60Hz. The device has a critical rate of rise of on-state current (di/dt) of 500 A/μs and a critical rate of rise of off-state voltage (dv/dt) of 1000 V/μs. Isolation breakdown voltage is 2500 V AC for one minute. Operating junction temperature ranges from -40°C to +125°C.
Feature Summary
- New gate design provides higher di/dt capability, rated at 2.5 times that of existing products.
- Less-layered internal structure improves heat dissipation through lower thermal resistance.
- Soldering on both sides of chips increases long-term reliability compared to previous generations.
Applications
- Motor drives
- Servo controllers
- Power controllers
- UPS systems
- Soft starters
Procurement Notes
Verify the specific part number against official SanRex documentation to confirm electrical ratings and physical dimensions. Ensure mounting torque specifications are strictly followed during installation to maintain performance and safety standards. Cross-reference datasheet parameters with system requirements before finalizing procurement decisions.
Selection Notes
Select this component based on its 1600V blocking capability and 200A continuous current handling. Consider the improved thermal resistance for high-power applications requiring efficient heat dissipation. Evaluate the enhanced di/dt and dv/dt ratings for circuits prone to rapid voltage or current transients.
