Overview
The SanRex SCA200DA80 is a thyristor module featuring an integrated diode configuration. It supports a repetitive peak reverse voltage of 800 V and an average on-state current of 200 A at Tc=82°C. The device handles a surge on-state current of 6000 A and offers a critical rate of rise of off-state voltage (dv/dt) of 1000 V/μs. Thermal resistance from junction to case is 0.155 °C/W per element. Operating junction temperature ranges from -40°C to +125°C, with isolation breakdown voltage rated at 2500 V AC for one minute.
Feature Summary
- New gate design provides higher dv/dt capability compared to existing products
- Less-layered internal structure improves heat dissipation and reduces thermal resistance
- Soldering on both sides of chips increases long-term reliability
Applications
- Motor drives
- Servo controllers
- Power controllers
- UPS systems
- Soft starters
- Power supplies
Procurement Notes
Verify the specific part number suffix against official documentation to confirm voltage ratings and package compatibility. Confirm RoHS compliance status and UL file recognition E76102 during procurement. Ensure mounting torque specifications are met to maintain thermal performance and mechanical integrity.
Selection Notes
Select this module for applications requiring high dv/dt immunity and improved thermal management. Consider the 200 A average current rating and 800 V blocking voltage for power control circuits. Evaluate thermal resistance values for heatsink design to ensure operation within the specified junction temperature range.
