STMicroelectronics MSS40-1200 is a back-to-back SCR module designed for robust power control applications. This module features two SCRs in a single ISOTOP package, offering a 1.2 kV repetitive peak off-state voltage rating and a maximum RMS on-state current of 55 A. With a surge current capability of 400 A at 50 Hz, it reliably handles transient overloads. The device requires a maximum gate trigger current of 50 mA and a gate trigger voltage of 1.3 V for activation. Its ISOTOP chassis mount package ensures effective thermal management and simplified integration. Operating across a temperature range of -40°C to 125°C, the STMicroelectronics MSS40-1200 is suitable for demanding industrial power control systems, motor drives, and power supply applications.
