Revision 1/18/2001

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.
