SPE1211

SPE1211 Single-Line ESD Protection Array DESCRIPTION The SPE1211 are designed by TVS device that is to protect sensitive electronics from damage or latch-up due to ESD. They are designed for use in applications where board space is at a premium. SPE1211 will protect single line, and may be used on line where the signal polarities swing above and below ground. SPE1211 offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. SPE1211 may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small SOD-523 package makes them ideal for use in portable electronics such as cell phones, PDA’s, notebook computers, and digital cameras.

The device is unidirectional and may be used on lines where the signal polarity is above ground. The cathode band should be placed towards the line that is to be protected. 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. ★ 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. 2009/02/20 Ver.2 Page 4 SPE1211 Single-Line ESD Protection Array SOD-523 PACKAGE OUTLINE 2009/02/20 Ver.2 Page 5 SPE1211 Single-Line ESD Protection Array Information provided is alleged to be exact and consistent.
