UM5051DA
Single Line ESD Protection Diode Array
UM5051DA DFN2 0.6×0.3
General Description
The UM5051DA 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 UM5051DA
ESD protection diode protects sensitive semiconductor components from damage or upset due to
electrostatic discharge (ESD) and other voltage induced transient events. The UM5051DA is
available in DFN2 0.6mm×0.3mm package with working voltage 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,
±25kV contact discharge.
