UM5055
Single Line ESD Protection Diode Array
UM5055 SOD523
General Description
The UM5055 ESD protection diode is designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s. It features large cross-sectional area junctions for conducting high transient currents, offers 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 UM5055 ESD protection diode protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The UM5055 is available in SOD523 package and with working voltages of 5 volt.
