UESD6V8L1F
Low Capacitance Single Line ESD Protection Diode Array
UESD6V8L1F DFN2/FBP2 1.0×0.6
General Description
The UESD6V8L1F ESD 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 UESD6V8L1F ESD protection diode protects sensitive semiconductor components from
damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events.
The UESD6V8L1F is available in a DFN2/FBP2 1.0×0.6 (Compatible with SOD882) package
with working voltages of 5 volt.
It gives designer the flexibility to protect one unidirectional 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,
Level 4 (±15kV air, ±8kV contact discharge).
UESD6V8L1F is fabricated using dual diffusion technology offer low junction capacitance (20pF),
which is required in high speed signal protection application.
