Bidirectional TVS Arrayfor Protection of Eight Lines

The SMDAxxC-8 series of transient voltage suppres-sors are designed to protect components which areconnected to data and transmission lines from voltagesurges caused by ESD (electrostatic discharge), EFT(electrical fast transients), and lightning.

TVS diodes are characterized by their high surgecapability, low operating and clamping voltages, andfast response time. This makes them ideal for use asboard level protection of sensitive semiconductorcomponents. The SMDAxxC-8 is designed to providetransient suppression on multiple data lines and I/Oports. The low profile SO-14 design allows the user toprotect up to eight data and I/O lines with one pack-age. They are bidirectional device and may be used onlines where the normal operating voltage is above andbelow ground (i.e. -12V to +12V).

The SMDAxxC-8 TVS diode array will meet the surgerequirements of IEC 61000-4-2 (Formerly IEC 801-2),Level 4, Human Body Model for air and contactdischarge.
