UM5080T_16 Datasheet, PDF (1/6 Pages) Union Semiconductor, Inc. – Low Capacitance Bidirectional Single Line TVS Protection Diode

UM5080T
Low Capacitance Bidirectional Single Line
TVS Protection Diode
UM5080T TDFN2 1.0×0.6
General Description
The UM5080T 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 UM5080T TVS
protection diode protects sensitive semiconductor components from damage or upset due to
electrostatic discharge (ESD) and other voltage induced transient events. The UM5080T is
available in TDFN2 1.0×0.6 (compatible with SOD923/SOD882/CSP 1.0×0.6) package with
working voltages of 5 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, ±30kV air, ±30kV contact discharge.
