RClamp1851ZA - 18V ESD Protection

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.

Features

  • extremely good ESD protection characteristics including 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 typical capacitance (0.35pF at VR=0V) means that harmonic 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 Ultra Small RClamp® 1-Line, 18V ESD Protection Features ‹‹.
