DSL01-XXXSC5 Datasheet, PDF (1/3 Pages) STMicroelectronics – Secondary protection for DSL lines

DSL01-xxxSC5
Secondary protection for DSL lines
Data Brief
Features
■ Low capacitance devices:
– Delta C_typ = 3.5 pF
for 8 V, 10 V, 16 V, and 24 V
■ High surge capability: 30 A - 8/20 µs
■ Voltage: 8 V, 10 V, 16 V, and 24 V
■ RoHS package
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
Complies with the following standards
■ 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 µs
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.

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.
