SCA160DA80

SCRs - Modules 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.
