Semtech Expands Mobile Protection Platform with RClamp® 1851ZA – an 18V TVS Protection Device for Safeguarding NFC and RF Interfaces
Semtech’s RClamp1851ZA protects portable devices from dangerous ESD transients
Camarillo, California - January 28, 2016 -
Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the RClamp® 1851ZA, 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.”
Key Features of the RClamp1851ZA
- Transient protection for high-speed signal lines: IEC 61000-4-2 (ESD) ±20kV (air), ±17kV
- 18V working voltage protection for NFC resonator and other RF circuits
- Low insertion loss: less than 0.5 dB below 5 GHz operating frequency
