2-Line ESD Protection Array
The SPE0512 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. SPE0512 will protect up to
two lines, and may be used on lines where the signal
polarities swing above and below ground.
SPE0512 offer desirable characteristics for board level
protection including fast response time, low operating and
clamping voltage, and no device degradation.
SPE0512 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 phones, PDA’s, notebook computers, and digital
Cellular Handsets and Accessories
Notebooks and Handhelds

Device Connection for Protection of Two Data Lines
SPE0512 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 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
1. Place the TVS near the input terminals or connectors to restrict transient coupling.

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.
