Semtech’s RClamp0564P TVS features ultra-low capacitance and clamping voltage to protect sensitive Ultra HD (4K) TVs from transient events

Camarillo, California - March 9, 2016 -

Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the RClamp®0564P, a 4-line integrated Transient Voltage Suppression (TVS) array designed to protect emerging high speed HDMI 2.0 interfaces against electrical transient threats. The RClamp0564P expands Semtech’s HDMI family of TVS devices targeted at the rapidly growing segment of Ultra HD (4K2K) systems featuring the latest HDMI 2.0 interface. The RClamp0564P is specifically engineered to meet the rigorous signal integrity requirements of HDMI 2.0 as well as deliver robust ESD protection for highly sensitive HDMI 2.0 chipsets.

Built on Semtech’s highly differentiated process technologies, the RClamp0564P achieves ultra-low clamping voltages for optimal transient protection and delivers ultra-low capacitance (0.17pF typical line-to-ground). In addition, its innovative flow-through package footprint offers a 20 percent PCB space savings over traditional 4-line HDMI devices to accommodate board-space constraints while dramatically improving overall clamping performance.

“To achieve maximum performance from today’s pluggable interfaces, chipmakers are continuing to push toward ever smaller process geometries, leading to controllers and SoC devices that are increasingly sensitive to ESD transient," said Rick Hansen, Product Marketing Director for Semtech’s Protection Product Group. "The RClamp0564P provides exceptional clamping performance to safeguard HDMI 2.0 interfaces against catastrophic ESD events, while its ultra-low capacitance enables superior signal robustness for the emerging class of Ultra HD products such as 4K television systems, media streaming devices, set top boxes and other similar consumer devices.”

Key Features of the RClamp0564P

  • Transient protection for high-speed data lines to: IEC 61000-4-2 (ESD) ±15kV (air), ±10kV (contact)
  • 5V working voltage protection
  • Low dynamic resistance: 0.65 Ohms
  • Ultra low capacitance (0.17pF line-to-ground)
  • Protects 4 I/O lines
  • Flow through 2.0mm x 1.0mm package
  • Pb Free and RoHS/WEEE compliant

Pricing and Availability

The RClamp0564P (order code: RClamp0564P.TNT) is available immediately in production quantities and is priced at $0.34 each in 10,000-piece lots. Semtech offers comprehensive design assistance, including field- and factory-based support. Datasheets, volume pricing, and delivery quotes, as well as evaluation kits and samples, are available at
