SPE0532

SPE0532 2-Line ESD Protection Array DESCRIPTION The SPE0532 are designed by TVS bi-direction 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. SPE0532 will protect 2-line, and may be used on line where the signal polarities swing above and below ground. SPE0532 offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. SPE0532 may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small SOT-23 package makes them ideal for use in portable electronics such as cell phones, PDA’s, notebook computers, and digital cameras.

The bidirection device is connected as follows: 1. The TVS protection of two I/O lines is achieved by connecting pins 1 and 2 to the data lines. Pin 3 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. 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: 1. Place the TVS near the input terminals or connectors to restrict transient coupling. 2. Minimize the path length between the TVS and the protected line. 3. Minimize all conductive loops including power and ground loops. 4. The ESD transient return path to ground should be kept as short as possible. 5. Never run critical signals near board edges. 6. Use ground planes whenever possible. 2008/08/30 Ver.1 Page 5 SPE0532 2-Line ESD Protection Array SOT-23 PACKAGE OUTLINE 2008/08/30 Ver.1 Page 6 SPE0532 2-Line ESD Protection Array Information provided is alleged to be exact and consistent.
