TVS Diode Arrays (SPA Diodes) Lightning Surge Protection - LC03-3.3 Series RoHS GREEN Pb LC03-3.3 Series 3.3V 150A Diode Array 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.
