The new SP03A-3.3 provides overvoltage protection for applications such as 10/100/1000 BaseT Ethernet, T3/E3 DS3 interfaces, ADSL2+, and VDSL2+. 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. RoHS compliant MS-012 surface mount package (JEDEC SO-8) Low insertion loss, log-linear capacitance Combined longitudinal and metallic protection Lightning Protection, IEC61000-4-5, 150 A (8/20 us) Clamping speed of nanoseconds UL 94V-0 epoxy molding Low clamping voltage
