TVS Diode Array
For ESD and Latch-Up Protection
PRELIMINARY
PROTECTION PRODUCTS
Features
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.
u ESD protection for data lines to
IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact)
u Small package for use in portable electronics
u Protects five I/O lines
u Working voltage: 5V
u Low leakage current
u Low operating and clamping voltages
u Solid-state silicon-avalanche technology
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.
Mechanical Characteristics
u EIAJ SC70-6L package
u Molding compound flammability rating: UL 94V-0
u Marking : Marking Code
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, PDAs, notebook comput-
ers, and digital cameras.
u Packaging : Tape and Reel per EIA 481
Applications
u Cellular Handsets & Accessories
u Cordless Phones
u Personal Digital Assistants (PDAs)
u Notebooks & Handhelds
u Portable Instrumentation
u Digital Cameras
u Peripherals
u MP3 Players
