Description

DSL02 is designed to protect DSL line drivers

against surges defined in worldwide

telecommunication standards. This device

protects line drivers of various systems such as

ADSL and VDSL. The low capacitance makes it

suitable from ADSL to VDSL data rates.

DSL02 is able to survive severe conditions even

when used with downgraded or oscillating gas

tube.

DSL02 is also suitable to be used on other lines

when IEC61000-4-5 surge capability is required.

DSL02 is packaged in a SOT23-5L.
