SD05C through SD24C Single Line TVS Diode for ESD Protection in Portable Electronics PRELIMINARY PROTECTION PRODUCTSPROTECTION PRODUCTS Features Description The SDxxC TVS diodes are designed to replace multi- 350 Watts peak pulse power (t = 8/20s) p layer varistors (MLVs) in portable applications such as Transient protection for data lines to cell phones, notebook computers, and PDAs. They IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) offer superior electrical characteristics such as lower IEC 61000-4-4 (EFT) 40A (5/50ns) clamping voltage and no device degradation when IEC 61000-4-5 (Lightning) 24A (8/20s) compared to MLVs. The SDxxC series TVS diodes are Small package for use in portable electronics designed to protect sensitive semiconductor compo- Suitable replacement for MLVs in ESD protection nents from damage or upset due to electrostatic applications discharge (ESD) and other voltage induced transient Protects one I/O or power line events. Low clamping voltage Working voltages: 5V, 12V, 15V, 24V The SDxxC is in a SOD-323 package and will protect Low leakage current one bidirectional line. They are available with working Solid-state silicon avalanche technology voltages of 5 - 24 volts. These devices will fit on the same PCB pad area as an 0805 MLV device. They give Mechanical Characteristics the designer the flexibility to protect one line in applica- tions where arrays are not practical. Additionally, it EIAJ SOD-323 package may be sprinkled around the board in applications Molding compound flammability rating: UL 94V-0 where board space is at a premium. Marking : Marking code Packaging : Tape and Reel per EIA 481 They may may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, Applications 8kV contact discharge).
