Mechanical Characteristics

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.
