1 RClamp582B Low Capacitance RClamp ESD and EOS Protection PROTECTION PRODUCTS Description The RClamp 582B transient voltage suppressor is specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), and EFT (electrical fast transients). The RClamp 582B features high peak pulse current capability (I PP =15A, tp=8/2μs) for use in applications that require high surge immunity testing. It has a maximum capacitance of only 1.2pF (pin 1 or 2 to pin). They may be used to meet the ESD immunity requirements of IEC (±kv air, ±25kV contact discharge). Each device can be configured to protect 1 bidirectional line or two unidirectional lines. These devices are in a small SC-75 (SOT-52) package and feature a lead-free, matte tin finish. They are compatible with both lead free and SnPb assembly techniques. The combination of small size, low capacitance, and high level of surge protection makes them a flexible solution for protection of USB 2., LVDS, and video interfaces.

5 Application Information Device Connection Options This device is optimized for protection of two high speed data lines. The device is connected as follows: Protection of two lines is achieved by connecting data lines at pins 1 & 2. Pin is connected to ground. The connection to ground should be made directly to a ground plane. The path length should also be kept as short as possible to minimize parasitic inductance. 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 1% 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. Figure 1.
