Description
The SLV series of transient voltage suppressors are
designed to protect low voltage, state-of-the-art CMOS
semiconductors from transients caused by electro-
static discharge (ESD), cable discharge events (CDE),
lightning and other induced voltage surges.
The devices are constructed using Semtechs propri-
etary EPD process technology. The EPD process pro-
vides low standoff voltages with significant reductions
in leakage currents and capacitance over silicon-
avalanche diode processes. The SLVU2.8-4 features
integrated low capacitance compensation diodes that
reduce the maximum capacitance to <8pF per line.
This, combined with low leakage current, means signal
integrity is preserved in high-speed applications such
as 10/100 Ethernet.
The SLVU2.8-4 is in an SO-8 package and may be used
to protect two high-speed line pairs. The flow-thru
design minimizes trace inductance and reduces voltage
overshoot associated with ESD events. The low
clamping voltage of the SLVU2.8-4 minimizes the
stress on the protected IC.
The SLV series TVS diodes will meet the surge require-
ments of IEC 61000-4-2, Level 4.

Applications Information
Device Connection for Protection of Four Data Lines
Electronic equipment is susceptible to transient distur-
bances from a variety of sources including: ESD to an
open connector or interface, direct or nearby lightning
strikes to cables and wires, and charged cables hot
plugged into I/O ports. The SLVU2.8-4 is designed to
protect sensitive components from damage and latch-
up which may result from such transient events. The
SLVU2.8-4 can be configured to protect two high-
speed line pairs. The device is connected as follows:
SLVU2.8-4 Circuit Diagram
1 . Protection of two high-speed line pairs:
The SLVU2.8-4 is designed such that the data lines
are routed through the device. The first line pair
enters at pins 1 and 2 and exit at pins 8 and 7
respectively. The second line pair enters at pins 3
and 4 and exits at pins 6 and 5. The traces must
be connected at the bottom of the device as
shown.
Circuit Board Layout Recommendations for Suppres-
sion of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
l Place the SLVU2.8-4 near the input terminals or
connectors to restrict transient coupling.
l Minimize the path length between the TVS and the
protected line.
l Minimize all conductive loops including power and
ground loops.
l The ESD transient return path to ground should be
kept as short as possible.
l Never run critical signals near board edges.
l Use ground planes whenever possible.
