USBLC6-4SC6

VERY LOW CAPACITANCE

ESD PROTECTION

REV. 2

SOT23-6L

February 2005

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 VBUS

■ 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 VBUS. 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
