As high-speed transceiver ICs implemented on ever-shrinking silicon geometries become increasingly sensitive to transient voltage spikes, the need for high performance protection circuitry is becoming even more critical. These ICs require ultra-low clamping voltage protection while also presenting a minimal loading capacitance. Based on Semtech’s FemtoClamp technology, the RClamp3371ZC utilizes an advanced ultra-low capacitance TVS silicon process for achieving the highest performance ESD protection for high speed data communication channels. RClamp3371ZC is housed in a very small 0201 package giving board designers key space savings and a high degree of layout flexibility.
“USB Type-C interfaces are rapidly becoming the data transfer standard for communications and handheld devices,” says Tee Lim, Product Marketing Director for Semtech’s Protection Products Group. “Semtech’s RClamp3371ZC gives the hardware design community a highly differentiated protection device optimized for safeguarding these important high speed USB data ports.”
Key Features of the RClamp3371ZC include transient protection for high speed data lines according to IEC 61000-4-2 (ESD) ±17kV (air), ±10kV (contact); IEC 61000-4-4 (EFT) 40A (5/50ns); IEC 61000-4-5 (lightning) 9A (8/20μs), 3.3V working voltage protection, surge capability up to 9A (tp=8/20μs), ultra-low capacitance (<0.25 pF max).
The Semtech RClamp3371ZC is available now in production quantities in a Pb-free and RoHS/WEEE compliant, ultra-small 0.62 x 0.32 x 0.25mm (0201) package. Semtech offers comprehensive design assistance, including field- and factory-based support. Volume pricing and delivery quotes, as well as evaluation kits and samples are also available.
