LC03-6R2

APPLICATIONS INFORMATION

The LC03- 6 ON Semiconductor's device is a TVS Diode
array designed to protect sensitive electronics such as
communications systems, computers, and computer
peripherals against damage due to transient overvoltage
conditions caused by lightning, electrostatic discharge
(ESD), and electrical fast transients (EFT). Because of its
relative low capacitance (<25 pf), it can be used in high speed
I/O data lines such as USB 1.1 ports.

The integrated design of the LC03-6 device offers high
surge rating, low capacitance steering diodes, and a TVS
diode integrated in a single package (SO-8). In addition, this
device offers compliance to Bellcore 1089 requirements
(intra-building).

LC03-6 Device's Configurations Options

Protection of Two High-speed I/O Data Lines

The LC03-6 device is able to protect two high speed data
lines against transient overvoltage conditions by driving
them to a fixed reference point for clamping purposes.
Depending in the application's requirements, the LC03-6
device can be configured for protection in either differential
mode (Line-to-Line) or common mode (Line-to-ground).
The Figure 5 shows the connection for Differential mode
(Line-to-Line) and Common mode (Line-to-Ground)
protection. The inputs and outputs of the I/O data lines are
connected at terminals 1 to 8, and 4 to 5 while the terminals
2, 3, 6 and 7 are connected to ground; for better performance,
it is recommended to minimize parasitic inductances by
using ground planes and minimizing the PCB trace lengths
for the ground return connections.

If differential protection is required by some particular
applications, then the configuration for differential protection
is made as shown in the Figure 6:

The Figure 7 shows a typical schematic for a T1/E1 line
card protection circuit. The LC03- 6 device is connected
between Tip and Ring on the transmit and receive line pairs.
it provides protection to metallic and common mode lightning
surges per Bellcore 1089 intra- building (For further
information, see Bellcore 1089 standard). A metallic voltage
is defined as a difference of potential between the T and R
terminals of a telecommunications pair. Currents caused by
lightning, in the absence of protector operation and with
balanced terminal equipment and telecommunications loop,
cause Tip and Ring conductors to attain the same potential
hence do not produce metallic transients. Common mode
surges are suppressed by the isolation of the transformer.

ESD Protection in USB 1.1 Port Applications

As we know, a USB port is composed of four lines. The
lines D+ and D- are used for bi-directional data
transmission, and the remaining two lines are reserved for
bus voltage and ground. Since USB is a hot plugging and
unplugging system, all its four lines have the risk to receive
ESD conditions in the real field of the application.

Typical ESD protection techniques are commonly formed
by the combination of different discrete semiconductor
products which make this technique obsolete and
non-ef ficient because the interconnections of the discrete
devices increase the parasitic inductance effects during a

transient condition which reduces significantly the
performance of the ESD protection circuit. The LC03-6
device provides a unique TVS Diode array designed to
protect two I/O data lines (single USB port) against damage
due to ESD conditions or transient voltage conditions.
Because of its low capacitance, it can be used in high speed
I/O data lines such as USB 1.1 components. In addition to its
low capacitance characteristics, the LC03-6 device from
ONSemiconductor complies with the most common
industrial standards for ESD, EFT and surge protection:
IEC61000-4-2, IEC61000-4-4, IEC61000-4-5.
