Union_UM5059_R03UM5059 Single Line ESD Protection Diode Array UM5059 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 DFN 2 1.0×0.6 (compatible with SOD923 & SOD882) package with working voltage……
