Providing a switching electronic shunt path when a single LED in an LED array fails as an open circuit, the PLED 6 Series from Littelfuse is an open LED protector that features a current range of 300 mA to 1.0 A. With an on-state voltage of 1.5 V, the open LED protector uses a 4-layered thyristor structure that automatically resets if the LED heals itself or is replaced and also features built-in surge immunity. It is RoHS compliant and halogen free. The open LED protector is available in two surface mount packages, the DO-214 and the Quad Flat Pak No-lead (QFN).
