SCA160DA80

Overview

The SanRex SCA160DA80 is a thyristor module featuring an integrated diode configuration. It provides a repetitive peak reverse voltage of 800 V and supports an average on-state current of 160 A at Tc=88°C. The device handles a surge on-state current of 5400 A with a critical rate of rise of on-state current (di/dt) of 500 A/μs. Thermal resistance from junction to case is 0.17 °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

• Features a new gate design that increases di/dt capability by 2.5 times compared to existing products.
• Utilizes a newly designed internal structure with fewer layers to improve heat dissipation and lower thermal resistance.
• Soldering on both sides of the chips enhances long-term reliability, extending life by two times over previous models.

Applications

• Motor drives
• Servo controllers
• Power controllers
• UPS systems
• Soft starters

Procurement Notes

Verify the specific part number suffix against official documentation to confirm voltage ratings and package variations. Confirm RoHS compliance status and UL file E76102 recognition requirements for your region. Ensure mounting torque specifications are strictly followed during installation to maintain thermal performance and mechanical integrity.

Selection Notes

Select this component for applications requiring high surge current handling and improved dv/dt immunity. Consider the 800V rating for appropriate circuit protection levels. Evaluate thermal management needs based on the specified junction-to-case thermal resistance values under continuous and sinusoidal operating conditions.
