DSL01-xxxSC5
Secondary protection for DSL lines
Data Brief
Features
Low capacitance devices: - Delta Ctyp = 3.5 pF for 8 V, 10 V, 16 V, and 24 V High surge capability: 30 A - 8/20 s Voltage: 8 V, 10 V, 16 V, and 24 V RoHS package

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 s

Description
This device combines a TransilTM used for low energy surges and a TrisilTM 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.
