Thyristor safeguards CVBS signal lines against damaging overvoltage transients

Post Date: March 6, 2019

Littelfuse has introduced the PxxxxS4xLRP Series SIDACtor Protection Thyristor, a robust solution for protecting 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 perfect for guarding a broad range of equipment needs in data line protection. The series offers a compact, surface-mount solution which simplifies designing it into PCB layout.

“For these applications, peak-to-peak signal voltage is within 1.1V, and driver IC Vcc voltage is less than 5V, so a protection component with a voltage higher than 6V is generally recommended,” said Jack Tung, product manager of SIDACtor Protection Thyristors, Electronics Business Unit at Littelfuse. “The PxxxxS4xLRP Series’ minimum operating voltage of 6V and 100A 5/310µS surge peak current capability meets this requirement, and its junction capacitance of less than 30pF is well-suited for 4.43MHz CVBS signals.”
