LC03-6
Low Capacitance Surface Mount TVS for
High-Speed Data Interfaces
PROTECTION PRODUCTS
Description
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), 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.
