SMDA05C-8 through SMDA24C-8 Bidirectional TVS Array for Protection of Eight Lines PROTECTION PRODUCTSPROTECTION PRODUCTS Features Description The SMDAxxC-8 series of transient voltage suppres- Transient protection for data lines to sors are designed to protect components which are IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) connected to data and transmission lines from voltage IEC 61000-4-4 (EFT) 40A (5/50ns) surges caused by electrostatic discharge (ESD), electri- IEC 61000-4-5 (Lightning) 12A (8/20 s) cal fast transients (EFT), and lightning. Small SO-14 surface mount package Protects eight I/O lines TVS diodes are characterized by their high surge Working voltages: 5V, 12V, 15V and 24V capability, low operating and clamping voltages, and Low leakage current fast response time. This makes them ideal for use as board level protection of sensitive semiconductor Low operating and clamping voltages components. The SMDAxxC-8 is designed to provide Solid-state silicon avalanche technology transient suppression on multiple data lines and I/O Mechanical Characteristics ports. The low profile SO-14 design allows the user to protect up to eight data and I/O lines with one pack- JEDEC SO-14 package age. They are bidirectional device and may be used on Molding compound flammability rating: UL 94V-0 lines where the normal operating voltage is above and Marking : Part Number, Logo, Date Code below ground (i.e. -12V to +12V). Packaging : Tape and Reel The SMDAxxC-8 TVS diode array will meet the surge Pb-Free, Halogen Free, RoHS/WEEE Compliant requirements of IEC 61000-4-2 (Formerly IEC 801-2), Applications Level 4, Human Body Model for air and contact discharge.
