This new P0080T023G5 is targeted for the tertiary or line
driver side protection position for VDSL2+ and ADSL2+
applications. This new low capacitance over voltage
protection does not require a bias voltage and is sufciently
robust for the chip-side position behind the coupling
transformer. This SOT23-5 solution, with its ow-through
design, minimizes PCB trace layout routing makes it
compatible with a variety of line drivers. Its low capacitance
makes it compatible with ADSL2 and VDSL2, and the
30MHz bandplan of VDSL2+.

The following schematics show alternate protection solutions
for a typical DSL interface that connects to outside wiring.
This surface mount SOT23-5 chip-side solution provides a
minimum footprint solution appropriate for high density card
designs. The P0080T023G5 will protect the interface from
lightning induced surges on the chip-side of the coupling
transformer. This tertiary protector may be preceded by lineside protection such as the TeleLink over-current protector

and the P0080T023G5 overvoltage protector. GDTs may also
be used on the line side of the coupling transformer. The
ow-through design of the SOT23-5 package is illustrated
below. If the inter winding capacitance of the transformer is
allowing some common mode events to get coupled across,
then the P0080T023G5 can be placed in a three chip mode,
as shown below for additional chip-side protection.
