SMDA05C THRU SMDA24C Bidirectional TVS Array for Protection of Four Lines PROTECTION PRODUCTS Features Description The SMDAxxC series of TVS arrays are designed to Transient protection for data lines to provide bidirectional protection for sensitive electronics IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) from damage or latch-up due to ESD, lightning and IEC 61000-4-4 (EFT) 40A (5/50ns) other voltage-induced transient events. Each device IEC 61000-4-5 (Lightning) 12A (8/20s) will protect four data or I/O lines. They are available Bidirectional protection with operating voltages of 5V, 12V, 15V and 24V. Small SO-8 package Protects four I/O lines Working voltages: 5V, 12V, 15V and 24V TVS diodes are solid-state devices designed specifically for transient suppression. They offer desirable charac- Low leakage current teristics for board level protection including fast re- Low operating and clamping voltages sponse time, low operating and clamping voltage and Solid-state silicon avalanche technology no device degradation. The low profile SO-8 package Mechanical Characteristics allows the user to protect up to four independent lines with one package. The SMDAxxC series is suitable JEDEC SO-8 package protection for sensitive semiconductors components Molding compound flammability rating: UL 94V-0 such as microprocessors, ASICs, transceivers, trans- Marking : Part number, date code, logo ducers, and CMOS memory. Packaging : Tube or Tape and Reel per EIA 481 The SMDAxxC series devices may be used to meet the Applications ESD immunity requirements of IEC 61000-4-2, level 4 Data and I/O Lines for air and contact discharge.
