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. The integrated TwinChip design utilizing SIDACtor technology provides an enhanced level of DSL driver protection while reducing any negative solid-state effects on the broadband signal. The TwinChip series provides low voltage protection with higher surge current ratings all in chip scale packaging.

The TwinChip SIDACtor configuration of this product provides bidirectional protection to limit DSL secondary line voltage to a safe 43V peak level.

It has surge current ratings up to 100A under lightning surge test conditions of 2x10µs (repetitive waveform). This 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.
