(Nasdaq: SMTC),
a leading supplier of analog and mixed-signal semiconductors, today
announced the RClamp®
, a high-performance, ultra-low capacitance transient voltage
suppression (TVS) device. The single-line RClamp1851ZA offers a unique
combination of features that protects Near Field Communications (NFC)
interfaces in rapidly growing, electronic payment systems.

Built on Semtech’s highly differentiated process technologies that
achieve the industry’s lowest clamping voltages, the RClamp1851ZA
delivers optimal transient protection for NFC resonator and radio
frequency (RF) interfaces. The RClamp1851ZA features a low, typical
dynamic resistance, which minimizes harmonic distortion, as well as best
in class, low ESD peak clamping voltage to prevent punch through
failures during an ESD event. It is housed in an ultra-small, fully
encapsulated package, which provides flexibility in circuit design and
eases PCB layout. To extend battery life of its end-user applications,
the device features low reverse leakage current of 1nA (typical).

“With the fast adoption of electronic payment systems on portable
devices, such as smartphones and smart watches, protecting the NFC
circuits on these devices ensures reliable operation and enhances user
experience,” said Rick Hansen, Product Marketing Director for Semtech’s
Protection Products. “The RClamp1851ZA expands Semtech’s RF protection
product family and offers electronics engineers the high reliability and
high performance in ESD protection that Semtech is known for.”
