DSLP biased series SOT23-6 SIDACtor protection thyristors from Littelfuse offer overvoltage protection superior to other market solutions for broadband communications applications with minimal effect on data signal integrity. Patented EpiSCR silicon crowbar technology ensures a capacitive loading characteristic that is ideal for use in high bandwidth applications. This technology also provides robust surge performance up to 35 A (8/20 μs). The compact SOT23-6 package with its flow-through lead frame design conserves valuable circuit board real estate and minimizes trace layout routing. Applications include tertiary and line driver side protection for digital subscriber line (DSL) equipment compliant with HD-SDI, HD-CVBS, ADSL2, ADSL2+, VDSL2, 35b Vplus, and G.fast data transmission standards.

Benefits
- Superior performance in surge capability ensures protection sufficient for even the most severe exposure G.fast applications (including GR-1089 Issue 6 inter-building requirements and ITU K20/21/45 enhanced external line recommendations)
- Provides low insertion loss and less distortion, particularly in higher data rate signals
- Reduces the impedance mismatching “stub-effect” caused by non-”flow-through” PCB trace connections and provides for an easier PCB design
- Better immunity to AC power cross issue compare to existing industrial clamping technology
- Easy design to fit various drivers
- Easy design for compatible foot print
