SD05 and SD12 Single Line TVS Diode for ESD Protection in Portable Electronics PROTECTION PRODUCTSPROTECTION PRODUCTS Features Description The SDxx TVS diodes are designed to replace multilayer 350 Watts peak pulse power (t = 8/20s) p varistors (MLVs) in portable applications such as cell Transient protection for data lines to phones, notebook computers, and PDAs. They offer IEC 61000-4-2 (ESD) 25kV (air), 10kV (contact) superior electrical characteristics such as lower clamp- IEC 61000-4-4 (EFT) 40A (5/50ns) ing voltage and no device degradation when compared IEC 61000-4-5 (Lightning) 24A (8/20s) to MLVs. The SDxx series TVS diodes are designed to Small package for use in portable electronics protect sensitive semiconductor components from Suitable replacement for MLVs in ESD protection damage or upset due to electrostatic discharge (ESD) applications and other voltage induced transient events. Protects one I/O or power line Low clamping voltage The SDxx is in a SOD-323 package and will protect one Working voltages: 5V and 12V unidirectional line. They are available with working Low leakage current voltages of 5 volts (SD05) and 12 volts (SD12). These Solid-state silicon-avalanche technology devices will fit on the same PCB pad area as an 0805 MLV device. They give the designer the flexibility to Mechanical Characteristics protect one line in applications where arrays are not EIAJ SOD-323 package practical. Additionally, it may be sprinkled around the Molding compound flammability rating: UL 94V-0 board in applications where board space is at a pre- Marking : Marking code, cathode band mium. Packaging : Tape and Reel per EIA 481 They may be used to meet the ESD immunity require- Applications ments of IEC 61000-4-2, Level 4 (15kV air, 8kV Cell Phone Handsets and Accessories contact discharge).
