Product Description  

The UM50125/50129 ESD protection diode is designed to replace multilayer varistors (MLVs) in portable instrumentation, notebook computers, digital power meter, digital camera and communication systems. 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 UM50125/50129 ESD protection diode protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The UM50125 is available in SOD523 package and the UM50129 is available in DFN2 1.0×0.6 (compatible with SOD923 & SOD882) packages, both with working voltages of 12 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.
