SMDA05CN-5 THRU SMDA15CN-5 PROTECTION PROTECTION PRODUCTS Description The SMDAxxCN-5 series of transient voltage suppressors are designed to protect components which are connected to data and transmission lines from voltage surges caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. TVS diodes are characterized by their high surge capability, low operating and clamping voltages, and fast response time. This makes them ideal for use as board level protection of sensitive semiconductor components. The SMDAxxCN-5 is designed to provide transient suppression on multiple data lines and I/O ports. The low profile SO-8 design allows the user to protect up to five data and I/O lines with one package. The SMDAxxCN-5 TVS diode array will meet the surge requirements of IEC 61000-4-2 (Formerly IEC 801-2), Level 4, “Human Body Model” for air and contact discharge.

The options for connecting the devices are as follows: 1. Bidirectional protection of four I/O lines is achieved by connecting pins 1, 2, 3, and 4 to the data lines. Pins 5, 6, 7, and 8 are connected to ground. The ground connection should be made directly to the ground plane for best results. The path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces. In this configuration, the device can withstand the maximum specified transient impulse on four lines simultaneously. 2. Bidirectional protection of five I/O lines is achieved by connecting pins 1, 2, 3, 4, and 5 to the data lines. Pins 6, 7, and 8 are connected to ground. The ground connection should be made directly to the circuit board ground plane for best results. In this configuration, the device can withstand the maximum rated transient impulse on any two lines simultaneously. Circuit Board Layout Recommendations for Suppression of ESD. Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are recommended: Place the TVS near the input terminals or connectors to restrict transient coupling. Minimize the path length between the TVS and the protected line. Minimize all conductive loops including power and ground loops. The ESD transient return path to ground should be kept as short as possible. Never run critical signals near board edges. Use ground planes whenever possible. To Protected IC Protection for Four Bidirectional Lines From Connector To Protected IC Protection for Five Bidirectional Lines From Connector Matte Tin Lead Finish Matte tin has become the industry standard lead-free replacement for SnPb lead finishes. A matte tin finish is composed of 100% tin solder with large grains. Since the solder volume on the leads is small compared to the solder paste volume that is placed on the land pattern of the PCB, the reflow profile will be determined by the requirements of the solder paste. Therefore, these devices are compatible with both lead-free and SnPb assembly techniques. In addition, unlike other lead-free compositions, matte tin does not have any added alloys that can cause degradation of the solder joint. 4 www.semtech.com  2005 Semtech Corp.
