描述 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 characteristics for board level protection including fast response 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 microprocessors, 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.
