SMDA05 THRU SMDA24
Unidirectional TVS Array
for Protection of Four Lines
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.
