TwinChip Achieves Greater Installation Efficiency

Thu, 04/10/2008 - 12:34pm


Littlefuse Inc’s TwinChip™ SDP Series provides improved DSL overvoltage protection. Achieving a fast switching and robust solution that prevents surge events from being shunted into the ground and power plane, the device provides broadband driver amplifier protection for the secondary side of coupling transformers. The device combines higher surge ratings with a smaller package size to meet OEM demands for higher component density and greater installation efficiency. The compact 0.118 inches× 0.118 inches× 0.39 inches QFN-packaged SDP series comes ready for surface mounting on DSL line cards with a tape and reel assembly. The configuration of this product provides bidirectional protection to limit DSL secondary line voltage to a safe 43 V peak level and achieves surge current ratings up to 100 A under lightning surge test conditions of 2 × 10μs (repetitive waveform) resulting in a lower and more stable off-state capacitance than typical thyristor overvoltage protection.
