New RailClamp (RClamp) RClamp3552T - a 3.5V,
Ultra-Low Capacitance Protection Array Safeguards LVDS and High-Speed
Differential Pairs in Consumer, Telecommunications and Industrial
Applications

Semtech
Corporation
(NASDAQ:SMTC), a leading supplier of analog and
mixed-signal semiconductors and advanced algorithms, today announced the
latest addition to the RClamp® platform, an ultra-low capacitance 3.5V
(Vrwm) transient voltage protection array designed to offer superior
protection for high-speed data signals, including USB 3.1 and LVDS, from
electrostatic discharge (ESD) and other voltage transients.

"The ESD protection margins on today's high-speed signal interfaces are
thinner than ever before," said Tee Lim, Product Marketing Director for
Semtech's Protection Products Group. "The newest member to our RClamp
portfolio, with its flow-through design, provides an excellent
low-clamping voltage ESD protection solution to safeguard high-speed
differential pairs, while at the same time preserving signal integrity
on highly sensitive data lines."

The RClamp3552T offers an extremely low ESD clamping voltage while
presenting a minimal capacitance of 0.40pF. This protection platform is
targeted at the emerging high-speed signal lines in consumer
electronics, telecommunications and industrial infrastructure. These
high-speed ports require increasingly lower ESD clamping voltage
thresholds with minimal capacitance loading from the ESD protection. The
new 2-line RClamp device achieves low ESD clamping voltage by using
Semtech's differentiated snap-back processes, which significantly limits
the transient energy presented to the circuit. Additionally, the
flow-through layout of the platform's package design enhances signal
integrity and gives system circuit designers maximum flexibility in the
PCB layout.

Key Features of the RClamp3552T

  • Transient protection for high-speed data lines: IEC 61000-4-2 (ESD)
    ±20kV (air), ±17kV (Contact); IEC 61000-4-4 (EFT) 4kV (5/50 ns); IEC
    61000-4-5 (Lightning) 4A (8/20 μs)
  • Low 3.5V working voltage protection
  • Safeguards two I/O data lines
  • Presents very low capacitance (<0.4 pF line-to-line)
  • Ultra-small 3-pin flow-through package: 1.0mm x 0.6mm
  • Pb Free and RoHS/WEEE compliant
