Overview

RailClamp® TVS diodes are designed to provide ESD and EOS protection on high-speed ports. RClamp®4021ZA is a 1-line, bidirectional device with a typical capacitance of only 0.45 pF and working voltage of 4.0V. It is manufactured using Semtech’s proprietary snap-back technology, which minimizes both ESD peak clamping and TLP clamping voltage. The dynamic resistance is extremely low (0.12 Ohms typical) providing optimum protection of sensitive circuits.
