SCE200DA80

Overview

The SCE200DA80 is a thyristor module from the SCE series manufactured by SanRex. It features an integrated thyristor structure with a new gate design, offering a critical di/dt of 500 A/μs and dv/dt of 1000 V/μs. The device supports a repetitive peak reverse voltage (VRRM) of 800 V and an average on-state current (IT(AV)) of 200 A at Tc=82°C. Key electrical parameters include a typical on-state voltage (VTM) of 1.4 V at IT=600A, a gate trigger current (IGT) of 100 mA, and a surge on-state current (ITSM) of 6000 A for a half-cycle. Thermal resistance from junction to case is 0.155 °C/W.

Feature Summary

• New gate design provides higher di/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 against official SanRex documentation to confirm ratings and pinout compatibility. Ensure mounting torque specifications are strictly followed during installation to maintain thermal performance and mechanical integrity. Check RoHS compliance status if required for your assembly process.

Selection Notes

Select this module when high di/dt and dv/dt immunity is required in power conversion circuits. Consider the 800 V blocking voltage and 200 A current rating relative to your system's peak loads. Evaluate thermal management needs based on the specified junction-to-case thermal resistance values under different conduction angles.
