SLVU28-4 Datasheet, PDF (1/8 Pages) Protek Devices – ULTRA LOW CAPACITANCE TVS ARRAY

PROTECTION PRODUCTS
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 Semtech’s 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.
