Overview
TClamp®0882S is specifically designed to provide secondary surge and electrostatic discharge (ESD) protection for G.Fast and other DSL circuit line drivers. These devices integrate low capacitance, surge-rated steering diodes with a high-power transient voltage suppressor (TVS). The TVS utilizes snap-back or “crow-bar” technology to minimize device clamping voltage and features high surge current capability of 30A (tp=8/20us). TClamp0882S capacitance is limited to 2.5pF maximum with a low typical capacitance variation over the operating voltage range, which ensures correct signal transmission on DSL lines. The biased bridge structure allows the device to be used in G.Fast, ADSL and VDSL applications.
