TVS array device protects two high speed data lines at once

Built on Semtech’s differentiated process technology that achieves low clamping voltages, the RClamp0552T delivers optimal transient protection and is housed in a 1.0x0.6x0.4mm package. In addition, the leads are spaced at a pitch of 0.34mm, and the flow-through design of the package simplifies PCB layout by allowing the traces to run straight through the device. The combination of small size, low capacitance and high level ESD protection makes the RClamp0552T a suitable solution for protecting high speed differential lines in portable applications such as mobile phones, fitness bands and wearable devices.  

The RClamp0552T delivers high performance with a small footprint. With increasing complexity of smartphones, PCB space and device thickness are key considerations when selecting components. Engineers value the small form factor of the RClamp0552T when protecting sensitive components in their designs.

The Pb free, Halogen free, RoHS/WEEE-compliant RClamp0552T provides 5V working voltage protection, low capacitance and dynamic resistance, respectively a typical 0.21pF and 0.9Ω. Transient protection for two high speed data lines is provided to IEC 61000-4-2 (ESD) ±17kV (air), ±17kV (contact).

“Robust ESD protection in a small package is more important to portable electronics manufacturers than ever before.” said Rick Hansen, Product Marketing Director, Protection Products, Semtech. “The RClamp0552T expands Semtech’s growing portable product family and offers ESD protection for high speed differential lines in a small and easy to use package.”

The RClamp0552T is available immediately in production quantities and is priced at $0.25 each in 10,000 piece lots. Semtech offers comprehensive design assistance, including field- and factory-based support.
