TClamp1272S
Low Capacitance TClamp®
Surge Protection for xDSL Interfaces
PROTECTION PRODUCTS - TransClamp®
Description
The TClamp®1272S provides dedicated line driver side
surge and ESD protection for ADSL and VDSL applica-
tions. It is designed to replace multiple discrete compo-
nents 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, surge-
rated compensation diodes with high power transient
voltage suppressors (TVS). The capacitance is limited to
5pF 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, RoHS/WEEE compliant,
SOT-23 package. The leads are finished with lead-free
matte tin. The flow- through package design simplifies
PCB layout.

Applications Information
Device Connection for Metallic Protection of High-
Speed Data Lines
The TClamp1272S is designed to protect high-speed
data lines from transient over-voltages which result from
lightning and ESD. The device is designed to protect one
line in common mode (Line-to-Ground) or one line pair
in metallic (Line-to-Line) mode. The part is designed
to allow straight-through connection, see the Wiring
Diagram opposite. Line 1A is connected at pin1 and its
trace can continue under the part and connect to pin6,
which is not connected internally to the part. A similar
connection can be made for Line 1B. For metallic mode
protection, the two lines are connected to pin1 and pin3.
For common mode protection, connect the line to pin1
and ground pin3 (or vice-versa). The ground connection
should be made directly to the ground plane for best
results. Bias voltage may be applied at pins 2 and 5 with
either polarity.
