SLVE28 Datasheet, PDF (1/7 Pages) Semtech Corporation – SLVE2.8 & SLVG2.8 EPD TVS DIODES FOR ESD AND LATCH-UP PROTECTION

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 SLVE2.8 & SLVG2.8
are in a SOT-143 package and have a low 2.8V work-
ing voltage. They may be used to protect one line in
differential or common mode. The “flow-thru” design
minimizes trace inductance and reduces voltage
overshoot associated with ESD events.
The SLV is specifically designed to protect low voltage
components such as Ethernet transceivers, laser
diodes, ASICs, and high-speed RAM. The low clamping
voltage of the SLV minimizes the stress on the pro-
tected IC.
The SLV series TVS diodes will exceed the surge re-
quirements of IEC 61000-4-2, Level 4.
