UM5060
Bidirectional Single Line TVS Protection Diode
UM5060 SOD523
General Description
The UM5060 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 UM5060 TVS protection diode protects
sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and
other voltage induced transient events. The UM5060 is available in SOD523 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.
