PROTECTION PRODUCTS - TransClamp Description
A TransClamp is a low capacitance TVS array designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and Lightning. These devices integrate low capacitance, surge-rated compensation diodes with a high power transient voltage suppressor (TVS). The compensation diodes are arranged in a bridge pattern allowing the device to be connected in common mode and/or differential mode. This allows the designer maximum flexibility and reduces parts count. The capacitance of the device is limited to 12pF maximum from line-to-line to ensure correct signal transmission on high-speed lines. These devices may be used to meet Bellcore GR-1089CORE short-haul (intra-building) surge requirements and will withstand a minimum 100 A surge for a 2/10s pulse. The TClampTM0602N is in a 10-pin, RoHS/WEEE compliant, SLP2626P10 package. It measures 2.6 x 2.6 x 0.60mm. The leads are spaced at a pitch of 0.5mm and are finished with lead-free NiPdAu. They are particularly well suited for applications where board space is at a premium such as integrated connectors/ magnetics and T1/E1 equipment.

PROTECTION PRODUCTS Applications Information
Device Connection Options for Protection of Two High-Speed Data Lines These devices are designed to protect two high-speed data lines (one differential pair) from transient overvoltages which result from lightning and ESD. They can be configured to protect in differential (Line-to-Line) and common (Line-to-Ground) mode. Data line inputs/ outputs are connected at pins 1, 2 and 3, and 8, 9 and 10 as shown. For proper operation, pins 1 - 3 must be connected together and pins 8 - 10 must be connected together. Pins 4, 5, 6, and 7 left unconnected. For differential operation, the center tab is also left not connected. For common mode operation, the center tab is connected to ground. The ground connection should be made directly to a ground plane on the board for best results. The use of multiple vias is recommnded for reduced ground loop inductance. Circuit Diagram
