SDP Series SOT23-5, SIDACtor Protection Thyristors

Littelfuse SDP series thyristors offer low-capacitance DSL tertiary and general I/O protection functions

Image of Littelfuse's SDP Series SOT23-5, SIDACtor Protection ThyristorsThe new Littelfuse SIDACtor series is targeted for the tertiary or line-driver side-protection position for VDSL2+, ADSL2 applications and general I/O protection functions. This new low-capacitance, over-voltage protection does not require a bias voltage and is sufficiently robust for the chip-side position behind the coupling transformer.

This SOT23-5 solution, with its flow-through design, minimizes PCB trace-layout routing, while its four different stand-off voltage values offer compatibility with a variety of line drivers. Its low capacitance makes it compatible with ADSL2 and VDSL2, and the 30 MHz bandplan of VDSL2+.

Applications include tertiary protection, line-driver side protection, ADSL2 protection, VDSL2+, and Ethernet interface protection.

Features and Benefits

  • SOT23-5 surface-mount package
  • Low insertion loss
  • Low capacitance
  • Bidirectional transient voltage protection
  • Robust surge rating
  • Starts to switch in nanoseconds
  • RoHS compliant
