High-speed ESD protector

Circuit & System Protection
The new ESD7004 from ON Semiconductor is specifically designed to preserve signal integrity in high-speed applications such as USB 3.0 (5 Gbps) and eSATA (up to 6 Gbps). The device offers an ultra low 0,4 pF rating, while maintaining extremely low ESD clamping voltage.
As high-speed interfaces exceed 5 Gbps, a few tenths of a picofarad capacitance can have a major effect on the signal integrity of the data being transmitted. By lowering the capacitance down to 0,4 pF typical (0,5 pF maximum) the ESD7004 offers an ESD protection solution that has virtually no effect on eye diagrams of USB 3.0 at 5 Gbps and eSATA at 6 Gbps. In addition, these parts maintain less than 1 db insertion loss at over 8 GHz during S21 measurements, ensuring negligible effect on high-speed data transmission.
Utilising ON Semiconductor’s patented ESD protection silicon which incorporates innovative isolation techniques, the ESD7004 boasts clamping voltages at 11,4 V or less during transmission line pulse (TLP) ±8 A testing which safeguards chipsets using small geometries and low voltage tolerances, common for high-speed datalines. An ESD rating of 15 kV contact per the IEC61000-4-2 standard and low turn-on resistance during ESD events ensures that the most sensitive chipsets will be safe from ESD threats.
The IC is offered in the uDFN 2,5 x 1,0 x 0,5 mm 10-pin package which integrates four lines of protection in a flow-through routing pinout that enables board designers to route traces easily with minimal impact to impedance matching.
