UM5052DA
Single Line Bi-directional ESD Protection Diode Array
UM5052DA DFN2 0.6×0.3
General Description
The UM5052DA ESD protection diode is designed to replace multilayer varistors (MLVs) in
portable applications such as cell phones, notebook computers, and PDA’s. They 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
UM5052DA ESD protection diode protects sensitive semiconductor components from damage or
upset due to electrostatic discharge (ESD) and other voltage induced transient events. The
UM5052DA is available in DFN2 0.6mm×0.3mm package with working voltage of 5 volt. It gives
designer the flexibility to protect one bidirectional 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.
