描述 Description

RClamp?01811ZA is a low capacitance FemtoClampTM

ESD protection device specifically designed to protect

high-speed differential lines. It offers desirable

characteristics for board level protection including fast

response time, low operating and clamping voltage, and

no device degradation.

RClamp01811ZA ESD protection characteristics include

low typical dynamic resistance of 0.13 Ohms, low peak

ESD clamping voltage, and high ESD withstand voltage

per IEC 61000-4-2 (±12kV contact). It also features

high EOS peak pulse current rating of 8A (tp = 8/20μs).

RClamp01811ZA maximum capacitance is limited to

1.2pF with low insertion loss at 2.5GHz and 5GHz.

RClamp01811ZA is in a DFN 0.60 x 0.30 x 0.25mm 2-lead

package. The small package gives the designer the

flexibility to protect single lines in space-constrained

applications.
