Features
Description
u 1500 watts peak pulse power (tp = 10/1000µs)
u Transient protection for high speed data lines to
IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact)
IEC 61000-4-5 (Lightning) 95A (8/20µs)
Bellcore 1089 (Outer-Building),
The LC01-6 transient voltage suppressor is designed to
protect components which are connected to high
speed telecommunication lines from voltage surges
caused by lightning, electrostatic discharge (ESD), and
electrical fast transients (EFT).
100A (10/1000µs), 500A (2/10µs)
TVS diodes are ideal for use as board level protection
of sensitive semiconductor components. The LC01-6
is designed for metallic mode, secondary line side
protection in digital line card applications. It features
solid-state silicon-avalanche technology for unmatched
transient protection without device degradation. The
LC01-6 combines TVS diodes with low capacitance
compensation diodes to provide an integrated, low
capacitance protection solution. Additional features
include sub-nanosecond response time, a low operat-
ing voltage of 6 volts, and low clamping voltage.

Applications Information
Device Connection Options for Protection of High-
Speed Data Lines
The LC01-6 is designed to protect high-speed data
lines from transient over-voltages which result from
lightning and ESD. The device is designed to protect
one line pair in differential (Line-to-Line) mode. Pins 1-
8 are connected to line 1 and pins 9-16 are connected
to line 2 as shown. All pins should be connected for
best results.
T1/E1 Linecard Protection
A typical long-haul T1/E1 linecard protection circuit is
shown below. The LC01-6 is connected between Tip &
Ring on the transmit and receive line pairs. It provides
protection to metallic (line-to-line) lightning surges per
Bellcore 1089 and FCC Part 68. Depending on the
application, a high voltage crowbar device (not shown)
such as a gas discharge tube (GDT) or TVS Thyristor
may be used to suppress common mode (line-to-
ground) surges. To complete the protection circuit, the
SRDA05-4 (or SRDA3.3-4 for 3.3V supplies) is em-
ployed as the secondary IC side protection element.
This device helps prevent the transceiver from latching
up by providing fine clamping of transients that are
coupled through the transformer. Positive temperature
coefficient (PTC) resistors or fuses are also required for
AC power cross protection. For further information,
reference Semtech application note AN97-10.
