LC03-3.3_08 Datasheet, PDF (1/7 Pages) Semtech Corporation – Low Capacitance 3.3 Volt TVS for High Speed Interfaces

PROTECTION PRODUCTS
Description
The LC03-3.3 transient voltage suppressor is designed
to protect components which are connected to high
speed data and 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-
3.3 combines a TVS diode with a rectifier bridge to
provide transient protection in both common and
differential mode with a single device. The LC03-3.3
utilizes Semtech’s EPD technology for superior electri-
cal characteristics at 3.3 volts. The capacitance of the
device is minimized to ensure correct signal transmis-
sion on high speed lines.
The LC03-3.3 meets the short-haul (intra-building)
transient immunity requirements of Bellcore 1089 for
telecommunications applications.
