PROTECTION PRODUCTS - RailClamp®
Description
RClamp® TVS diodes are designed to protect sensitive
electronics from damage or latch-up due to ESD. They
are designed to replace multilayer varistors (MLVs) in
portable applications such as cell phones, notebook
computers, and other portable electronics. This device
offers desirable characteristics for board level protection
including fast response time, low operating and clamp-
ing voltage, and no device degradation.
RClamp®1851ZA is specifically designed for protection of
Near Field Communications (NFC) interfaces. It features
extremely good ESD protection characteristics includ-
ing a low typical dynamic resistance of 0.16 Ohms, low
peak ESD clamping voltage, and high ESD withstand
voltage (+/-17kV contact per IEC 61000-4-2). Low typi-
cal capacitance (0.35pF at VR=0V) means that harmon-
ic distortion the the RF signal is minimized. This device
is bidirectional and has a working voltage of 18V for use
on NFC resonator circuits without signal clipping.

RClamp1851ZA is in a 2-pin SLP0603P2X3F package
measuring 0.6 x 0.3 mm with a nominal height of only
0.25mm. Leads are finished with NiAu. The small pack-
age gives the designer the flexibility to protect single
lines in applications where arrays are not practical. The
combination of small size and high ESD surge capability
makes them ideal for use in portable applications such
as cellular phones, digital cameras, and tablet PCâs.
