General Description
The UM5055 ESD protection diode is designed to replace multilayer varistors
(MLVs) in portable applications such as cell phones, notebook computers, and
PDA’s. It features large cross-sectional area junctions for conducting high
transient currents, offers 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
UM5055 ESD protection diode protects sensitive semiconductor components from
damage or upset due to electrostatic discharge (ESD) and other voltage induced
transient events. The UM5055 is available in SOD523 package and with working
voltages of 5 volt.
Features
Transient protection for data & power lines to IEC 61000-4-2 (ESD) ±15kV
(air), ±8kV (contact)
