UM5059
Description
The UM5059 ESD protection diode is designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook puters, 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 pared to MLVs. The UM5059 ESD protection diode protects sensitive semiconductor ponents 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 (patible 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...
