Description
This LC03-3.3 series provides overvoltage protection for
applications such as 10/100/1000 BaseT Ethernet, and
T3/E3 interfaces. This new protector combines the TVS
diode element with a diode rectifier bridge to provide both
longitudinal and differential protection in one package.
This design results in a capacitive loading characteristic
that is log-linear with respect to the signal voltage across
the device. This reduces intermodulation (IM) distortion
caused by a typical solid-state protection solution. The
application schematic provides the connection information
and the LC03-3.3 is rated for GR-1089, intra-building
transient immunity requirements for telecommunication
installations.
Features
• Lightning Protection,
IEC61000-4-5, 150A
(tp=8/20µs)
• EFT, IEC61000-4-4, 40A
(tp=5/50ns)
• Low insertion loss, log-
linear capacitance
• Low clamping voltage
• SOIC-8 surface mount
package (JEDEC MS-012)
• Combined longitudinal
and metallic protection
• Clamping speed of
nanoseconds
• UL 94V-0 epoxy molding
• RoHS compliant
Applications
• T1/E1 Line cards
• T3/E3 and DS3 Interfaces
• STS-1 Interfaces
• 10/100/1000 BaseT
Ethernet

This schematic shows a high-speed data interface
protection solution. The LC03-3.3BTG is compatible with
the intra-building surge requirements of Telcordia’s GR-
1089-CORE, and the Basic Level Recommendations of
ITU K.20 and K.21. The TeleLink fuse provides overcurrent
protection for the long term 50/60 Hz power fault events.
