Littelfuse Inc. S8040R is a standard recovery Silicon Controlled Rectifier (SCR) designed for high-voltage, high-current applications. This through-hole component features an 800V repetitive peak off-state voltage and a 40A RMS on-state current rating. The S8040R SCR exhibits a maximum on-state voltage of 1.8V and a gate trigger current requirement of 40mA. It is packaged in a TO-220 configuration with a non-isolated tab, suitable for power control and switching applications. The device offers a 24-hour, 100% blocking state with a maximum off-state current of 20µA. Its non-repetitive surge current capability reaches 430A at 50Hz and 520A at 60Hz. Operating temperature range is -40°C to 125°C. This component is commonly utilized in industrial power supplies, motor control, and lighting control systems.
