Littelfuse offers a DSLP Biased series of thyristors which provides over-voltage protection for high data-rate communications links such as HD-SDI, HD-CVBS, VDSL2, ADSL2, ADSL2+ and G.fast with a minimal effect on data signals.

The innovative design of the thyristors results in a capacitive-loading characteristic which is compatible with these high-bandwidth applications. This technology provides a better surge capability than traditional clamping silicon technology provides. This reduces the possibility of field failures caused by AC power faults or multiple transient surges, without compromising signal integrity.

• Balanced voltage protection
• 35A 8/20μs surge capability
• Low insertion loss
