Broadband Optimized SIDACtor Protection Thyristors

Littelfuse Broadband Optimized SIDACtor Protection Thyristors focus on addressing the performance and regulatory requirements of broadband equipment. The Broadband Optimized family, with its wide range of solutions, provides applications with the options needed to address the unique protection needs of DSL equipment (up to VDSL) as well as Ethernet (up to 1000baseT). Optimization is accomplished using proprietary and patented approaches that minimize the negative effects of device capacitance on broadband signals. The Littelfuse Broadband components provide an overvoltage protection solution that helps applications comply with Telcordia GR-1089 Issue 4, and ITU-T recommendations K.20, K.21, K.44, and K.45.
