RClamp0524S RailClamp Low Capacitance TVS Diode Array PROTECTION PRODUCTS Features Description RailClamps are low capacitance TVS arrays designed ESD protection for high-speed data lines to to protect high speed data interfaces. This series has IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) been specifically designed to protect sensitive compo- IEC 61000-4-4 (EFT) 40A (5/50ns) nents which are connected to data and transmission Array of surge rated diodes with internal TVS Diode lines from overvoltage caused by ESD (electrostatic Small package saves board space discharge), CDE (Cable Discharge Events), and EFT Protects four I/O lines (electrical fast transients). Low capacitance: 5pF maximum The unique design incorporates two identical circuits. Low clamping voltage Each circuit is comprised of surge rated, low capaci- Low operating voltage: 5.0V tance steering diodes and a TVS diode in a single Solid-state silicon-avalanche technology package. During transient conditions, the steering diodes direct the transient current to ground. The Mechanical Characteristics internal TVS diode clamps the transient voltage to a JEDEC SOT-23 6L package safe level. The RClamp0524S has a low maximum Molding compound flammability rating: UL 94V-0 capacitance of only 5pF per line. Each device will Marking : S05 protect up to four data lines. The dual circuits make it Packaging : Tape and Reel ideal for applications like power over Ethernet (PoE) RoHS/WEEE Compliant where each signal pair sits at a different potential. TM The RClamp 0524S is in a 6-pin, RoHS/WEEE compli- Applications ant, SOT-23 package. The leads are finished with lead- PoE free matte tin. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 Monitors and Flat Panel Displays (15kV air, 8kV contact discharge).
