SMS05 through SMS24
TVS Diode Array
For ESD and Latch-Up Protection
PROTECTION PRODUCTS
Description
The SMS series of TVS arrays are designed to protect
sensitive electronics from damage or latch-up due to
ESD and other voltage-induced transient events. Each
device will protect up to four lines. They are available
with operating voltages of 5V, 12V, 15V and 24V. 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-
sectional area junctions for conducting high transient
currents. They offer desirable characteristics for board
level protection including fast response time, low
operating and clamping voltage and no device degrada-
tion.
The SMS series devices may be used to meet the
immunity requirements of IEC 61000-4-2, level 4. The
low cost SOT23-6L package makes them ideal for use
in portable electronics such as cell phones, PDA’s, and
notebook computers.
