SMDA05 through SMDA24
PROTECTION PRODUCTS
Description
The SMDAxx series of TVS arrays are designed to provide
undirectional protection for sensitive electronics from
damage or latch-up due to ESD, lightning, and other
voltage-induced transient events. Each device will
protect four data or I/O lines. They are available with
operating voltages of 5V, 12V, 15V and 24V.
TVS diodes are solid-state devices designed specifically
for transient suppression. They offer desirable charac-
teristics for board level protection including fast re-
sponse time, low operating and clamping voltage and no
device degradation. The low profile SO-8 package allows
the user to protect up to four independent lines with one
package. The SMDAxx series is suitable protection for
sensitive semiconductors components such as micropro-
cessors, ASICs, transceivers, transducers, and CMOS
memory.
The SMDAxx series devices may be used to meet the
ESD immunity requirements of IEC 61000-4-2, level 4 for
air and contact discharge.
