uClamp1201H TM Clamp 1-Line ESD Protection TM PROTECTION PRODUCTS - MicroClampPROTECTION PRODUCTS Features Description TM The Clamp series of TVS arrays are designed to protect Transient protection for data lines to sensitive electronics from damage or latch-up due to ESD. IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) It is designed to replace multilayer varistors (MLVs) in por- IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) table applications such as cell phones, notebook comput- Cable Discharge Event (CDE) ers, and PDAs. It features large cross-sectional area junc- Ultra-small SOD-523 package (1.7 x 0.9 x 0.7mm) tions for conducting high transient currents. It offers Protects one I/O or power line superior electrical characteristics such as lower clamp- Low clamping voltage ing voltage and no device degradation when compared Working voltage: 12V to MLVs. They offer desirable characteristics for board Low leakage current level protection including fast response time, low oper- Solid-state silicon-avalanche technology ating and clamping voltage, and no device degradation. TM The Clamp 1201H is in a 2-pin, RoHS compliant, Mechanical Characteristics SOD-523 package. The leads are finished with lead- EIAJ SOD-523 package free matte tin. Each device will protect one line oper- Molding compound flammability rating: UL 94V-0 ating at 12 volts. It gives the designer the flexibility to Marking: Marking code, cathode band protect single lines in applications where arrays are not Packaging: Tape and Reel per EIA 481 practical. They may be used to meet the ESD immunity Lead Finish: Matte tin requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). The combination of small size and RoHS Compliant high ESD surge capability makes them ideal for use in Applications portable applications such as cellular phones, digital cameras, and MP3 players.
