DSL01-xxxSC5
Secondary protection for DSL lines
Data Brief

Features

Low capacitance devices: Delta Ctyp = 3.5 pF for 8 V, 12 V, 16 V, and 24 V High surge capability: 30 A - 8/20 us Voltage: 8 V, 12 V, 16 V, and 24 V RoHS package

4 5 2 1
SOT23-5L (SC-59)

Benefits

Transil mode will clamp ESD and low energy surges without disturbing line drivers during transmission while high energy surges will be short circuited to avoid line driver damage. The low capacitance makes it suitable for ADSL2+ and VDSL signals

Line drivers

DSL01

Complies with the following standards

Line Drivers Ring

IEC 61000-4-2, Level 4: 15 kV (air discharge) 8 kV (contact discharge) MIL STD 883G-Method 3015-7: Class 3 25 kV (human body model) IEC 61000-4-5, Level 2: 24 A, 8/20 us

Description
This device combines a Transil used for low energy surges and a Trisil for high energy surges. This combination provides a surge / capacitance trade-off compatible with high debit rates such as ADSL2+ and VDSL. The combination on the same die makes it compatible with SOT23-5L package.

Applications

Secondary protection to be located after the transformer of ADSL and VDSL modem either on central office or subscriber side. Replaces crowbar protection located on primary side.
