They are designed for use in applications where board space is at a premium. Each device will protect up to five lines. They are unidirectional devices and may be used on lines where the signal polarities are above ground. TVS diodes are solid-state devices designed specifically for transient suppression. They feature large cross-sectional area junctions for conducting high transient currents. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. The SMF series devices may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small SC70 package makes them ideal for use in portable electronics such as cell phones, PDA’s, notebook computers, and digital cameras. ## Features - ESD protection for data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) - Small package for use in portable electronics - Protects five I/O lines - Working voltage: 5V - Low leakage current - Low operating and clamping voltages - Solid-state silicon-avalanche technology ## Mechanical Characteristics - EIAJ SC70-6L package - Molding compound flammability rating: UL 94V-0 - Marking : Marking Code - Packaging : Tape and Reel per EIA 481 ## Applications - Cellular Handsets and Accessories - Cordless Phones - Personal Digital Assistants (PDA’s) - Notebooks and Handhelds - Portable Instrumentation - Digital Cameras - Peripherals - MP3 Players ## Circuit Diagram **==> picture [265 x 209] intentionally omitted <==** **----- Start of picture text -----**

www.semtech.com  2004 Semtech Corp. 3 SMF05C ## PROTECTION PRODUCTS ## PRELIMINARY ## Applications Information ## Device Connection for Protection of Five Data Lines The SMF05C is designed to protect up to five unidirectional data lines. The device is connected as follows: 1. Unidirectional protection of five I/O lines is achieved by connecting pins 1, 3, 4, 5 and 6 to the data lines. Pin 2 is connected to ground. The ground connection should be made directly to the ground plane for best results. The path length is kept as short as possible to reduce the effects of parasitic inductance in the board traces. ## Circuit Board Layout Recommendations for Suppression of ESD. Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are recommended: - Place the SMF05C near the input terminals or connectors to restrict transient coupling. - Minimize the path length between the SMF05C and the protected line. - Minimize all conductive loops including power and ground loops. - The ESD transient return path to ground should be kept as short as possible. - Never run critical signals near board edges. - Use ground planes whenever possible. ## Matte Tin Lead Finish Matte tin has become the industry standard lead-free replacement for SnPb lead finishes. A matte tin finish is composed of 100% tin solder with large grains. Since the solder volume on the leads is small compared to the solder paste volume that is placed on the land pattern of the PCB, the reflow profile will be determined by the requirements of the solder paste. Therefore, these devices are compatible with both lead-free and SnPb assembly techniques. In addition, unlike other lead-free compositions, matte tin does not have any added alloys that can cause degradation of the solder joint. ## SMF05C Circuit Diagram **==> picture [231 x 150] intentionally omitted <==** **----- Start of picture text -----**
