Littelfuse Intros Overvoltage Chip
DSL surge protectors.
Des Plaines, IL — Littelfuse, Inc. has expanded its Broadband Optimized SIDACtor product line by adding a new overvoltage protection series, the TwinChip SDP. The new configuration of this product provides bidirectional protection to limit DSL secondary line voltage to a safe 43V peak level. The device has surge current ratings up to 100A under lightning surge test conditions of 2x10µs (repetitive waveform).

The surge protection maintains the transformer-provided isolation, which typical rail clamps on the secondary side do not. Moreover, the TwinChip design results in a lower and more stable off-state capacitance than typical thyristor overvoltage protection, so there is less chance of signal waveform distortion.

This new product is a UL Recognized component (File #E133083), is RoHS-compliant, and has no inherent wear-out mechanisms when operated within its specified parameters.

The TwinChip SDP Series combines higher surge ratings with a smaller package size to meet OEM demands for higher component density and greater installation efficiency. Its compact QFN (Quad Flatpak No-Lead) package has typical dimensions of 0.118 x 0.118 x 0.39-in., and comes ready for surface mounting on DSL line cards with a tape and reel assembly. The OEM reel quantity is 5000.
