1 / 7 page PROTECTION PRODUCTS 1 www.semtech.com PRELIMINARY PROTECTION PRODUCTS SD05C through SD24C Single Line TVS Diode for ESD Protection in Portable Electronics Description Features Schematic & PIN Configuration Revision 07/06/04 Applications Mechanical Characteristics The SDxxC TVS diodes are designed to replace multi- layer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s. They offer superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. The SDxxC series TVS diodes are designed to protect sensitive semiconductor compo- nents from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The SDxxC is in a SOD-323 package and will protect one bidirectional line. They are available with working voltages of 5 - 24 volts. These devices will fit on the same PCB pad area as an 0805 MLV device. They give the designer the flexibility to protect one line in applica- tions where arrays are not practical. Additionally, it may be “sprinkled” around the board in applications where board space is at a premium. They may may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). 350 Watts peak pulse power (t p = 8/20µs) Transient protection for data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) IEC 61000-4-5 (Lightning) 24A (8/20µs) Small package for use in portable electronics Suitable replacement for MLV’s in ESD protection applications Protects one I/O or power line Low clamping voltage Working voltages: 5V, 12V, 15V, 24V Low leakage current Solid-state silicon avalanche technology EIAJ SOD-323 package Molding compound flammability rating: UL 94V-0 Marking : Marking code Packaging : Tape and Reel per EIA 481 Cell Phone Handsets and Accessories Microprocessor based equipment Personal Digital Assistants (PDA’s) Notebooks, Desktops, and Servers Portable Instrumentation Pagers Peripherals SOD-323 (Top View) 12 |
