1 www.semtech.com PROTECTION PRODUCTS RClamp0524S Low Capacitance TVS Diode Array Description Features Package Dimensions Equivalent Circuit and PIN Configuration Revision 04/24/2008 RailClamps® are low capacitance TVS arrays designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive compo- nents which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). The unique design incorporates two identical circuits. Each circuit is comprised of surge rated, low capaci- tance steering diodes and a TVS diode in a single package. During transient conditions, the steering diodes direct the transient current to ground. The internal TVS diode clamps the transient voltage to a safe level. The RClamp0524S has a low maximum capacitance of only 5pF per line. Each device will protect up to four data lines. The dual circuits make it ideal for applications like power over Ethernet (PoE) where each signal pair sits at a different potential. The RClamp TM0524S is in a 6-pin, RoHS/WEEE compli- ant, SOT-23 package. The leads are finished with lead- free matte tin. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge).
