TVS Diode Array

For ESD and Latch-Up Protection

Revision 9/2000

The SMF series TVS arrays are designed to protect sen-

sitive electronics from damage or latch-up due to ESD

and other voltage-induced transient events. They are

designed for use in applications where board space is at

a premium. Each device will protect up to four lines.

They are unidirectional devices and may be used on lines

where the signal polarities are above ground.

TVS diodes are solid-state devices designed specifically

for transient suppression. They feature large cross-sec-

tional area junctions for conducting high transient cur-

rents. They offer desirable characteristics for board level

protection including fast response time, low operating

and clamping voltage, and no device degradation.

The SMF series devices may be used to meet the immu-

nity requirements of IEC 61000-4-2, level 4. The small

SC70 package makes them ideal for use in portable elec-

tronics such as cell phones, PDA’s, notebook comput-

ers, and digital cameras.
