RClamp1521P Ultra-Low Capacitance 1-Line ESD protection PROTECTION PRODUCTS PROTECTION PRODUCTS - RailClamp Features Description The RailClamp family is a series of ultra low capacitance Transient protection for data lines to Transient Voltage Suppressors (TVS) designed to protect IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) high speed data interfaces. This series has been specifi- IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) cally designed to protect sensitive components which are Cable Discharge Event (CDE) connected to high-speed data and transmission lines Ultra-small package (1.0 x 0.6 x 0.5mm) from overvoltage caused by ESD (electrostatic discharge), Protects one data or I/O line CDE (Cable Discharge Events), and EFT (electrical fast Low capacitance: 0.3pF typical transients). Low clamping voltage TM The RClamp 1521P has a maximum capacitance of Low operating voltage: 15V only 0.5pF. This allows it to be used on circuits operat- Solid-state silicon-avalanche technology ing in excess of 3GHz without signal attenuation. They may be used to meet the ESD immunity requirements Mechanical Characteristics of IEC 61000-4-2, Level 4 (15kV air, 8kV contact SLP1006P2 package discharge). Molding compound flammability rating: UL 94V-0 The RClamp1521P is in a 2-pin, RoHS/WEEE compliant, Marking: Marking code SLP1006P2 package measuring 1.0 x 0.6 x 0.5mm. Packaging : Tape and Reel The leads are spaced at a pitch of 0.65mm and feature Lead Finish: NiPdAu a lead-free finish. Each device will protect one high- RoHS/WEEE Compliant speed line operating at 15 volts. It gives the designer the flexibility to protect single lines in applications Applications where arrays are not practical. The combination of Cellular Handsets & Accessories small size, low capacitance, and high ESD surge USB Ports capability makes them ideal for use in applications such as cellular phones and high-power USB.
