TClamp2502N
Low Capacitance TVS
for Ethernet and Telecom Interfaces
PROTECTION PRODUCTS - TransClampΤΜ
Description
A TransClampΤΜ is a low capacitance TVS array designed
to protect high speed data interfaces. This series has
been specifically designed to protect sensitive compo-
nents which are connected to data and transmission
lines from overvoltage caused by ESD (electrostatic
discharge), CDE (Cable Discharge Events), and Light-
ning.
These devices integrate low capacitance, surge-rated
compensation diodes with a high power transient
voltage suppressor (TVS). The compensation diodes
are arranged in a bridge pattern allowing the device to
be connected in common mode and/or differential
mode. This allows the designer maximum flexibility and
reduces parts count. The capacitance of the device is
limited to 12pF maximum from line-to-line to ensure
correct signal transmission on high-speed lines.
These devices may be used to meet Telcordia GR-1089-
CORE short-haul (intra-building) surge requirements and
will withstand a minimum 100 A surge for a 2/10μs
pulse.
The TClampTM2502N is in a 10-pin, RoHS/WEEE
compliant, SLP2626P10 package. It measures 2.6 x
2.6 x 0.60mm. The leads are spaced at a pitch of
0.5mm and are finished with lead-free NiPdAu. They
are particularly well suited for applications where board
space is at a premium such as integrated connectors/
magnetics and carrier class Ethernet equipment.

Applications Information
Device Connection Options for Protection of Two
High-Speed Data Lines
TClamp2502N is designed to protect two high-speed
data lines (one differential pair) from transient over-
voltages which result from lightning and ESD. They can
be configured to protect in differential (Line-to-Line)
and common (Line-to-Ground) mode. Data line inputs/
outputs are connected at pins 1, 2 and 3, and 8, 9
and 10 as shown. For proper operation, pins 1 - 3
must be connected together and pins 8 - 10 must be
connected together. Pins 4, 5, 6, and 7 may be left
unconnected. For differential operation, the center tab is
also left not connected. For common mode operation,
the center tab is connected to ground. The ground
connection should be made directly to a ground plane
on the board for best results. The use of multiple vias
is recommended for reduced ground loop inductance.
