Mechanical Characteristics The SMDA 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 SMDA05-6 is designed to provide transient suppression on multiple data lines and I/O ports. It is designed to operate on 5V digital lines. The low profile SO-8 design allows the user to protect up to six data and I/O lines with one package. The SMDA05-6 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.

4 2006 Semtech Corp. www.semtech.com PROTECTION PRODUCTS SMDA05-6 Circuit Diagram Connection Diagram Device Connection for Protection of Six Data Lines The SMDA05-6 is designed to protect up to 6 data or I/O lines operating at 5 volts. They are unidirectional devices and may be used on lines where the signal polarities are above ground (i.e. 0 to 5V). The device is connected as follows: z Pins 1, 2, 3, 4, 5 and 8 are connected to the lines that are to be protected. Pins 6 and 7 are con- nected to ground. The ground connections should be made directly to the ground plane for best results. The path length is kept as short as pos- sible to reduce the effects of parasitic inductance in the board traces. Circuit Board Layout Recommendations for Suppres- sion of ESD. Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are recommended: z Place the TVS near the input terminals or connec- tors to restrict transient coupling. z Minimize the path length between the TVS and the protected line. z Minimize all conductive loops including power and ground loops. z The ESD transient return path to ground should be kept as short as possible. z Never run critical signals near board edges. z Use ground planes whenever possible. 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 com- pared 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. 123 4 5678 DATA IN DATA OUT DATA IN DATA OUT Applications Information
