LC01-6
Low Capacitance TVS for High-Speed
Telecommunication Systems
PROTECTION PRODUCTS
Description
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).
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.
The LC01-6 is suitable for use on T1/E1 and xDSL
interfaces in equipment such as base stations, routers,
and channel service units. The LC01-6 meets the long-
haul (outer-building) transient immunity requirements
of Bellcore 1089, FCC Part 68 (Type A and B surges),
and IEC 61000-4-5.
