Description
LC03-6
Low Capacitance TVS for High-Speed
Data Interfaces
Features
The LC03-6 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) ,
cable discharge events (CDE) , and electrical fast
transients (EFT) .
TVS diodes are ideal for use as board level protection
of sensitive semiconductor components. The LC03-6
combines a TVS diode with a rectifier bridge to provide
transient protection in both common and differential
mode with a single device. The capacitance of the
device is minimized (< 25pF) to ensure correct signal
transmission on high speed lines . The LC03-6 meets
the short-haul (intra-building) transient immunity
requirements of Bellcore 1089 for telecommunications
applications.
The SO-8 surface mount package allows flexibility in
the design of crowded PC boards.
