Littelfuse SIDACtor protects the thyristor

This new SIDAC tor family of thyristors is targeted for VDSL2+, ADSL2 applications and general I/O protection functions in either the three stage or line driver side protection position. This new low-capacitance overvoltage protection does not require a bias voltage and is robust enough for the chip side position behind the coupling transformer.

This SOT23-5 solution, with its circulation design, minimizes PCB routing layout, while its four different isolation voltage values provide compatibility with a variety of line drivers. Its low capacitance makes it compatible with ADSL2 and VDSL2, as well as VDSL2+ 's 30MHz band planning
