TwinChip Achieves Greater Installation EfficiencywebwebWith a construction that prevents surge events from being shunted into the ground and power plane, Littlefuse’s TwinChip SDP Series SIDACtor protection device provides improved DSL overvoltage protection as well as broadband driver amplifier protection for the secondary side of coupling transformers. The bidirectional device limits DSL secondary line voltage to a 43V peak with a surge current rating up to 100A for a lower and more stable off-state capacitance than typical thyristor overvoltage protection. The SMT  0.118" × 0.118" × 0.39” protection devices are RoHS compliant, and have no inherent wear-out mechanisms when operated within specified parameters.
