Littelfuse Inc. S8055M is a standard recovery Silicon Controlled Rectifier (SCR) designed for high-power switching applications. This through-hole component features an 800V repetitive peak off-state voltage (VDRM) and a 55A RMS on-state current (IT(RMS)) rating, with an average on-state current (IT(AV)) of 35A. The S8055M exhibits a maximum on-state voltage drop (VTM) of 1.8V and requires a gate trigger current (IGT) of 40mA. It maintains a low off-state leakage current (IDRM) of 20µA and a hold current (IH) of 60mA. With non-isolated tab construction in a TO-218 package, it is rated for surge currents up to 650A at 60Hz. Operating across a temperature range of -40°C to 125°C, the Littelfuse Inc. S8055M is suitable for power control systems, industrial motor drives, and general power switching applications.
