TCLAMP1272S
Description
The TClamp®1272S provides dedicated line driver side surge and ESD protection for ADSL and VDSL applications. It is designed to replace multiple discrete ponents in portable applications. They feature high surge current capability of 20A (tp=8/20us) and low clamping voltage making them ideal for use on the IC side of a coupling transformer. The TClamp1272S integrates low capacitance, surgerated pensation diodes with high power transient voltage suppressors (TVS). The capacitance is limited to 5p F maximum to ensure correct signal transmission on high-speed lines. Two internal bias diodes are provided for the TVS diode. The TClamp1272S is in a 6-pin, Ro HS/WEEE pliant, SOT-23 package. The leads are finished with lead-free matte tin. The flow- through package design simplifies PCB layout.
