Description

This new SIDACtor series is targeted for the tertiary or line driver side protection position for VDSL2+, ADSL2 applications and general I/O protection functions. This new low capacitance over voltage protection does not require a bias voltage and is sufciently robust for the chip-side position behind the coupling transformer.

This SOT23-5 solution, with its ow-through design, minimizes PCB trace layout routing, while its four different stand-off voltage values offer compatibility with a variety of line drivers. Its low capacitance makes it compatible with ADSL2 and VDSL2, and the 30MHz bandplan of VDSL2+.

Features & Beneﬁts

• Lower overshooting protection than clamping

• SOT23-5 surface mount package

• Low insertion loss

• Low capacitance

SDP-xxx Application example

SIDACtor

Protection Thyristors

Teccor® brand SIDACtor® DSL Protection Devices

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 SDP-xxx0T023 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 SDP3500Q38CB 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 SDP-xxx0T023 can be placed in a three chip mode, as shown below for additional chip-side protection.
