TVS Diode Array
For ESD and Latch-Up Protection
PROTECTION PRODUCTS
Description
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.
