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 components 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. Two internal bias diodes are provided for the TVS diode. The leads are finished with lead-free matte tin. The flow- through package design simplifies PCB layout. FEATURES
