SDC15 PPRROOTTEECCTTIIOONN PPRROODDUUCCTTSS Applications Information Device Connection for Protection of One Data Line Device Schematic and Pin Configuration The SDC15 is designed to protect one data or I/O line operating at ±12 volts. Connection options are as follows: (cid:122) Common mode protection: Pin 1 is connected to the data line and pin 2 is connected to ground. For best results, this pin should be connected directly to a ground plane on the board. The path length should be kept as short as possible to minimize parasitic inductance. Pin 3 is not connected. (cid:122) Differential protection: Pin 1 is connected to one line and pin 2 is connected to the second line. Pin 3 is not connected. Circuit Board Layout Recommendations for Suppres- RS-232 Transceiver Protection Example sion of ESD. Good circuit board layout is critical for the suppression of fast rise-time transients such as ESD. The following guidelines are recommended: (cid:122) Place the SDC15 near the input terminals or connectors to restrict transient coupling. (cid:122) Minimize the path length between the SDC15 and the protected line. (cid:122) Minimize all conductive loops including power and ground loops. (cid:122) The ESD transient return path to ground should be kept as short as possible. (cid:122) Never run critical signals near board edges. (cid:122) 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.  2004 Semtech Corp. 4 www.semtech.com
