Dual-Line ESD Protection Array STE051 2 Working voltage 5V
DESCRIPTION
The STE051 2 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 ia at a premium. STE0512 will protect up to two lines, and may be used on lines where the signal polarities swing above and below ground. STE0512 offer desirable c haracteristics for board level protection including fast response time, low operating and clamping voltage without device degradation. STE0512 may be used to meet the immunity requirements of IEC 61000 -4-2, level 4. The small SOT-523 package makes them ideal for use in portable electronics such as cell phone, PDA’s, notebook comp uters, digital cameras and MP3.

Dual-Line ESD Protection Array STE0512 Working voltage 5V APPLICATION NOTE Device Connection for Protection of Two Data Lines STE0512 is designed to protect up to two data lines. The device is connected as follows: 1. The TVS protection of two I/O lines is achieved by connecting pins 1,2 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. Psgr 4 STANSON TECHNOLOGY TEL: (650) 9389294 FAX: (650) 9389295
