Littelfuse SIDACtor Protection Thyristor Safeguards CVBS Signal Lines Against Damaging Overvoltage Transients

Littelfuse released the first PxxxxS4xLRP Series SIDACtor Protection Thyristor. The new Thyristor is touted as a robust solution for protecting Composite Video Blanking Sync (CVBS) signal lines and ports from damaging overvoltage transients. The combination of 6V operating voltage and 100A 5/310µs surge peak current capability and a low junction capacitance rating make the P0080S4BLRP ideal for protecting a wide range of equipment needs data line protection.

The PxxxxS4xLRP Series provides a compact, surface-mount solution which simplifies designing it into PCB layout. The new thyristor released is well fit for the applications such as TV/camera CVBS cables, data communications, Set Top Boxes (STBs), RS-485, RS-232 data lines, CAN Bus. The thyristor comes with operating voltage of 6V with 100A 10/700µS, 4kV surge peak current capability, and junction capacitance of < 30pF make it well-suited for low voltage signal line protection applications, such as 4.43MHz CVBS signals, RS-484, RS-323 data lines or CAN Bus.

The PxxxxS4xLRP Series SIDACtor Protection Thyristor offers these key benefits:

  • Low voltage overshoot
  • Low on-state voltage
  • Does not degrade surge capability after multiple surge events within its ratings
  • Fails short circuit when surged in excess of ratings
  • Low capacitance
  • 4kV 10/700 surge protection capability

The samples of the PxxxxS4xLRP Series SIDACtor Protection Thyristor are available through authorized distributors worldwide in SOD-123FL packaging in tape and reel format in quantities of 3,000 samples.
