4-Line ESD Protection Array
The SPE0504 are designed by TVS array 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. SPE0504 will protect up to four
line, and may be used on lines where the signal polarities
swing above and below ground.
SPE0504 offer desirable characteristics for board level
protection including fast response time, low operating and
clamping voltage, and no device degradation.
SPE0504 may be used to meet the immunity requirements
of IEC 61000-4-2, level 4. The small SOT-23-6L package
makes them ideal for use in portable electronics such as
cell phones, PDA’s, notebook computers, and digital

‹ Transient protection for data lines to
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
IEC 61000-4-4 (EFT) 40A (5/50ns)
‹ Protects four I/O lines
‹ Working voltage: 5V
‹ Low leakage current
‹ Low operating and clamping voltages

4-Line ESD Protection Array
Device Connection for Protection of Four Data Lines
SPE0504 is designed to protect up to four data lines. The device is connected as follows:
1. The TVS protection of four I/O lines is achieved by connecting pins 1, 3, 4 and 6 to the data lines. Pin 2 and 5
are 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.
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.
