UM5084
Low Capacitance Bidirectional Single Line TVS
Protection Diode
UM5084 DFN2
General Description
The UM5084 TVS 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 UM5084 TVS
protection diode protects sensitive semiconductor components from damage or upset due to
electrostatic discharge (ESD) and other voltage induced transient events. The UM5084 is
available in DFN2 1.0×0.6 (compatible with SOD923/SOD882/CSP 1.0×0.6) package with
working voltages of 12 volt. It gives designer the flexibility to protect bidirectional single 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, ±15kV air, ±8kV contact discharge.
