SMF05C_04 Datasheet, PDF (1/7 Pages) Semtech Corporation – 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 five 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.
