This new broadband protection device from Littelfuse
provides overvoltage protection for applications such
as 10/100/1000 BaseT Ethernet, T3/E3 DS3 interfaces,
ADSL2+, and VDSL2+. This new protector combines the
TVS diode element with a diode rectifier bridge to provide
both longitudinal and differential protection in one package.
This design innovation results in a capacitive loading
characteristic that is log-linear with respect to the signal
voltage across the device. This reduces intermodulation
(IM) distortion caused by a typical solid-state protection
solution. The application schematic provides the
connection information.
