1| www.semtech.com  2006 Semtech Corp. 3 SMDA05-6 ## PROTECTION PRODUCTS ## Applications Information ## Device Connection for Protection of Six Data Lines ## Circuit Diagram 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: - Pins 1, 2, 3, 4, 5 and 8 are connected to the lines that are to be protected. Pins 6 and 7 are connected to ground. The ground connections 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. **==> picture [130 x 105] intentionally omitted <==** ## Connection Diagram ## 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. ## 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. **==> picture [217 x 238] intentionally omitted <==** **----- Start of picture text -----**
