PROTECTION PRODUCTS _{- RailClamp}^®
Description
RailClamp^® TVS diodes are ultra low capacitance devices
designed to protect sensitive electronics from damage
or latch-up due to ESD, EFT, and EOS. They are designed
for use on high speed ports in applications such as cell
phones, notebook computers, and other portable elec-
tronics. These devices offer desirable characteristics for
board level protection including fast response time, low
operating and clamping voltage, and no device degrada-
tion.
RClamp^®2451ZA is specifically designed for protection
of Near Field Communications (NFC) interfaces. It fea-
tures extremely good ESD protection characteristics in-
cluding a low typical dynamic resistance of 0.16 Ohms
(typical), low peak ESD clamping voltage, and high ESD
withstand voltage (+/-14kV contact per IEC 61000-4-2).
Low typical capacitance (0.35pF at VR=0V) means that
RClamp2451ZA will not create harmonic distortion in the
RF signal. This device is bidirectional and has a working
voltage of 24V for use on NFC resonator circuits without
signal clipping.
RClamp2451ZA is in a 2-pin SLP0603P2X3F package
measuring 0.6 x 0.3 mm with a nominal height of
0.25mm. Leads are finished with lead-free NiAu. The
combination of working voltage, low dynamic resis-
tance, and low capacitance makes this device ideal for
use on NFC antenna ciruits, RF signal lines, and FM
antennas in portable devices.
