UM5059T
Single Line ESD Protection Diode Array
UM5059T DFN2 1.0×0.6
General Description
The UM5059T 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 UM5059T ESD
protection diode protects sensitive semiconductor components from damage or upset due to
electrostatic discharge (ESD) and other voltage induced transient events. The UM5059T is
available in DFN 2 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.
