RCLAMP2451ZATFT

The RCLAMP2451ZA 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 electronics. These devices offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation.RClamp2451ZA is specifically designed for protection of Near Field Communications (NFC) interfaces. It features extremely good ESD protection characteristics including 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 resistance, and low capacitance makes this device ideal for use on NFC antenna ciruits, RF signal lines, and FM antennas in portable devices.
