The four-line, 3.3V RClamp3324P interface protection offers designers increased margin with low ESD clamping voltage while minimizing loading capacitance to protect LVDS, Ethernet and USB 3.x lines. The part is housed in a 10-pin QFN package for a flexible flow-through layout ideal for optimizing trace routing to achieve signal integrity performance. The device exceeds the ESD requirements of the IEC61000-4-2 ESD immunity standard, achieving ±20kV air and ±17kV contact.
“Today’s high-speed data circuits are increasingly vulnerable to damage or latch-up from common electrostatic transients. Providing system robustness through lower clamping voltage protection solutions is critical,” said Tee Lim, Product Marketing Director for Semtech’s Protection Products Group. “The RClamp3324P leverages many of Semtech’s proprietary technology capabilities to offer product designers a device that clamps 25 to 50 percent lower than similar products on the market today.”
The transient interface protection for high-speed data lines is rated to IEC 61000-4-2 (ESD) ±20kV (air), ±17kV (contact); IEC 61000-4-4 (EFT) 4kV (5/50ns); IEC 61000-4-5 (lightning) 4.5A (8/20μs). It has a low capacitance of under 0.4pF typical line-to-line across the four lines in the 2.5 x 1.0 x 0.6 mm package.
The RClamp3324P.TCT is available immediately in production quantities. Semtech offers comprehensive design assistance, including field- and factory-based support. Data sheets, volume pricing, and delivery quotes, as well as evaluation kits and samples are available.
