Description

TClamp?xx82S are specifically designed to provide

secondary surge and 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).

TClampxx82S capacitance is limited to 2.5pF maximum

with a low typical capacitance variation over the

operating voltage range. This ensures correct signal

transmission on DSL lines. The biased bridge structure

allows the device to be used in G.Fast, ADSL, and VDSL

applications with with operating voltages 0f 8, 12, 20,

and 24Vp-p.

TClampxx82S is in a 6-pin SOT-23 package. The leads

are finished with lead-free matte tin. The flow- through

package design simplifies PCB layout.
