TVS Diode Arrays (SPA™ Family of Products)
Lightning Surge Protection - SP03A-3.3 Series
SP03A-3.3 Series 3.3V 150A Rail Clamp Array
RoHS
Pb GREEN
Description
This SP03A 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 SP03A
is rated for GR-1089, intra-building transient immunity
requirements for telecommunication installations.

T3/E3 PHY, etc.)
This schematic shows a high-speed data interface
protection solution. The SP03A-3.3 is compatible with the
intra-building surge requirements of Telcordia’s GR-1089CORE, 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.
