UM5075/5079
Single Line ESD Protection Diode Array
UM5075 SOD523
UM5079 DFN2/FBP2 1.0×0.6
General Description
The UM5075/5079 ESD protection diode is designed to replace multilayer varistors (MLVs) in
portable applications such as cell phones, notebook computers, and PDA’s. They feature large
cross-sectional area junctions for conducting high transient currents, offer desirable electrical
characteristics for board level protection, such as fast response time, lower operating voltage,
lower clamping voltage and no device degradation when compared to MLVs.
The UM5075/5079 ESD protection diode protects sensitive semiconductor components from
damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events.
The UM5075 is available in SOD523 package and the UM5079 is available in DFN2/FBP2
1.0×0.6mm2 (compatible with SOD882/SOD923) package, both with working voltage of 7 volt.
It gives designer the flexibility to protect one unidirectional line in applications where arrays are
not practical. Additionally, it may be “sprinkled” around the board in applications where board
space is at a premium. It may be used to meet the ESD immunity requirements of IEC 61000-4-2,
Level 4 (±15kV air, ±8kV contact discharge).

Applications Information
Device Connection Options
UM5075/5079 ESD protection diode is designed to protect one data, I/O, or power supply line.
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:
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. For multilayer printed-circuit boards, use ground
vias.
7. Keep parallel signal paths to a minimum.
8. Avoid running protection conductors in parallel with unprotected conductor.
9. Minimize all printed-circuit board conductive loops including power and ground loops.
10. Avoid using shared transient return paths to a common ground point.
