USBLC6-4SC6
VERY LOW CAPACITANCE
ESD PROTECTION
MAIN APPLICATIONS
■ USB2.0 ports up to 480Mb/s (high speed)
■ Backwards compatible with USB1.1 low and
full speed
■ Ethernet port: 10/100Mb/s
■ SIM card protection
■ Video line protection
■ Portable electronics
DESCRIPTION
The USBLC6-4SC6 is a monolithic Application
Specific Discrete dedicated to ESD protection of
high speed interfaces, such as USB2.0, Ethernet
links and Video lines.
Its very low line capacitance secures a high level
of signal integrity without compromising in
protecting sensitive chips against the most
stringent characterized ESD strikes.
FEATURES
■ 4 data lines protection
■ Protects V_BUS
■ Very low capacitance: 3pF typ.
■ SOT23-6L package
■ RoHS compliant
BENEFITS
■ Very low capacitance between lines to GND for
optimized data integrity and speed
■ Low PCB space consuming, 9mm² maximum
foot print
■ Enhanced ESD protection
■ IEC61000-4-2 level 4 compliance guaranteed
at device level, hence greater immunity at
system level
■ ESD protection of V_BUS. Allows ESD current
flowing to Ground when ESD event occurs on
data line
■ High reliability offered by monolithic integration
■ Low leakage current for longer operation of
battery powered devices
■ Fast response time
■ Consistent D+ / D- signal balance:
- Best capacitance matching tolerance
I/O to GND = 0.015pF
- Compliant with USB 2.0 requirements < 1pF
