STMicroelectronics MSS50-800 is an 800V, 70A, single-phase SCR module designed for demanding power control applications. This ISOTOP packaged module houses two back-to-back SCRs, facilitating efficient 1-phase controller functionality. It features a robust 70A RMS on-state current capability and handles significant surge currents with a 600A/630A rating at 50/60Hz. The module requires a maximum gate trigger current of 50mA and a gate trigger voltage of 1.3V, with a maximum holding current of 80mA. Operating across a temperature range of -40°C to 125°C, the MSS50-800 is suitable for industrial automation, power generation, and motor control systems. Its chassis mount design ensures reliable thermal management.
