SOT23-5 Package (Top View)

This range of devices is designed to protect xDSL line-driver

interfaces from overvoltages up to rated limits. Overvoltages are

normally caused by a.c. power-system or lightning-ﬂ ash distur-

bances which are induced or conducted onto the telephone line.

These symmetrical protectors are two-terminal thyristor-crowbar

devices. They can be used to protect between conductors, or a

pair of devices can be deployed to protect from line to ground.

Description

When placed between the xDSL line driver IC and the transformer, this protector will clamp and switch into a low-impedance state,

safely diverting the energy transferred by the xDSL coupling transformer. The low capacitance design makes this device suitable for

designs from ADSL all the way up to 30 MHz VDSL2.

Telecom ports need protection against Common Mode (Longitudinal) and Differential (Metallic) surges, to comply with international

standards such as ITU-T K.20, K.21 or K.45, Telcordia GR-1089-CORE and YD/T. Common Mode surges are resisted by the galvanic

isolation of the coupling transformer which is commonly rated to 2 kV or greater. Differential surges can be transmitted by the

transformer, and can stress the Line Driver Interface IC. As the xDSL interface circuit is designed to operate from 3 kHz to to 30 MHz,

nearby high frequency events - such as cable ﬂ ashover or primary protection activation - can generate damaging conditions for the

interface requiring this type of protection.

Please contact your Bourns representative if the protection voltage you require is not listed.
