Littelfuse Inc. S2055W81 is a standard recovery SCR with a 200V repetitive peak off-state voltage (VDRM). This through-hole component, housed in a TO-218X package with an isolated mounting tab, offers a 55A RMS on-state current (IT(RMS)) and a 35A average on-state current (IT(AV)). The peak non-repetitive surge current is rated at 550A at 50Hz and 650A at 60Hz. Gate trigger current (IGT) is a maximum of 40mA, with a maximum gate trigger voltage (VGT) of 1.5V. The on-state voltage (VTM) is a maximum of 1.8V. It is suitable for applications within a -40°C to 125°C operating temperature range. This device is commonly utilized in power control applications across industrial and appliance sectors.
