This makes them ideal for use as board level protection of sensitive semiconductor components. The SMDAxxC-5 is designed to provide transient suppression on multiple data lines and I/O ports. The low profile SO-8 design allows the user to protect up to five data and I/O lines with one package. - Working voltages: 5V, 12V, 15V and 24V - Low leakage current - Low operating and clamping voltages - Solid-state silicon avalanche technology ## Mechanical Characteristics - JEDEC SO-8 package - Molding compound flammability rating: UL 94V-0 - Marking : Part number, date code, logo The SMDAxxC-5 TVS diode array will meet the surge requirements of IEC 61000-4-2 (Formerly IEC 801-2), Level 4, “Human Body Model” for air and contact discharge. - Packaging : Tube or Tape and Reel per EIA 481 ## Applications - RS-232 and RS-422 Data Lines - Microprocessor Based Equipment - LAN/WAN Equipment - Notebooks, Desktops, and Servers - Instrumentation - Peripherals - Set Top Box - Serial and Parallel Ports ## Schematic and PIN Configuration **==> picture [157 x 130] intentionally omitted <==** ## SO-8 (Top View) www.semtech.com Revision 08/15/06 1 SMDA05C-5 THRU SMDA24C-5 ## PROTECTION PRODUCTS ## Absolute Maximum Rating |PROTECTION PRODUCTS

They are bidirectional devices and may be used on lines where the signal polarities are above and below ground. The SMDAxxC-5 TVS arrays employ a monolithic structure. Therefore, the working voltage (VRWM) and breakdown voltage (VBR) specifications apply to the differential voltage between any two data line pins. For example, the SMDA24C-5 is designed for a maximum voltage excursion of ±12V between any two data lines. The device is connected as follows: ## Circuit Diagram **==> picture [144 x 110] intentionally omitted <==** ## Connection Diagram - Pins 1, 2, 3, 4, and 5 are connected to the lines that are to be protected. Pin 8 is connected to ground. The ground connections 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. Pins 6 and 7 are not connected. ## 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 TVS near the input terminals or connectors to restrict transient coupling. - Minimize the path length between the TVS and the protected line. - Minimize all conductive loops including power and ground loops. **==> picture [217 x 222] intentionally omitted <==** **----- Start of picture text -----**

**----- End of picture text -----**
- 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. www.semtech.com  2004 Semtech Corp. 5 SMDA05C-5 THRU SMDA24C-5 ## PROTECTION PRODUCTS ## Outline Drawing - SO-8 **==> picture [492 x 185] intentionally omitted <==** **----- Start of picture text -----**
