UM5059
Single Line ESD Protection Diode Array
UM5059 DFN2 1.0×0.6
General Description
The UM5059 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 UM5059 ESD
protection diode protects sensitive semiconductor components from damage or upset due to
electrostatic discharge (ESD) and other voltage induced transient events. The UM5059 is
available in DFN2 1.0×0.6 (compatible with SOD923 & SOD882) package with working voltages
of 5 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, ±30kV air, ±30kV contact discharge.
