Littelfuse Inc. S4040R is a standard recovery SCR designed for high-power switching applications. This TO-220 package component offers a 400V repetitive peak off-state voltage (VDRM) and a 40A RMS on-state current (IT(AV)). The S4040R features a maximum gate trigger current (IGT) of 40mA and a holding current (IH) of 60mA, facilitating reliable turn-on characteristics. With a non-repetitive surge current rating of 430A at 50Hz and 520A at 60Hz, it provides robust performance under transient conditions. The on-state voltage drop (VTM) is a maximum of 1.8V at 40A. Operating across a temperature range of -40°C to 125°C, this through-hole mounted SCR is suitable for applications in industrial motor control, power supplies, and lighting control systems.
