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.
FEATUREs
● Transient protection for data lines to
IEC 61000-4-2 (ESD):
±15kV (air), ±8kV (contact)
● Small package for use in portable electronics
● Suitable replacement for MLV’s in ESD
