SLVDA2.8

Low Voltage TVS Diode Array

For ESD & Latch-Up Protection

Schematic & PIN Configuration

Revision 9/2000

The SLV series of transient voltage suppressors are

designed to protect low voltage semiconductor compo-

nents which are connected to data and transmission

lines from transients caused by electrostatic discharge

(ESD), 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 SLV series is specifi-

cally designed for protecting low voltage components

such as microprocessors, ASICs, I/O transceivers, and

high speed RAM. They provide ESD and latch-up

protection for power and I/O ports, microprocessor bus

interfaces, high speed data and video transmission

lines, and low power portable and wireless systems.

The SLV series TVS diodes will meet the surge require-

ments of IEC 61000-4-2, Level 4, “Human Body

Model” for air and contact discharge.

The low clamping voltage of the SLV minimizes the

stress on the protected transceiver. The SO-8 package

allows flexibility in the design of “crowded” circuit

boards.
