USBLC6-4SC6
VERY LOW CAPACITANCE
ESD PROTECTION
ASD
(Application Specific Devices)
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

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
