DSL70

Product Brief
DSL70
Superior ESD & Transient protection on ADSL, VDSL and other
broadband applications
Customer Values
Best in market protection solution supporting efficient BOM optimization.
 Highly reliable protection against
DSL70 is the protection diode selected to be integrated into the newest ADSL/
VDSL schematics from leading design groups.
Customers rate DSL70 as preferred solution because of its very low forward
voltage at high peak currents, lowest capacitance and overall superior surge
absorption performance than any other comparable device in the market. This
benchmark performance in combination with a very competitive price makes
the DSL70 the device of choice in the protection arena, well ahead
of others.
transients and ESD events exceeding
IEC standard
 Lowest forward-clamping voltage while handling the highest surge currents
 Lowest capacitance to fulfill quality
requirements of DSL high-speed
signal
 Optimized to enable compliance
with telecommunication regulatory
requirements like:
