Nexperia, the expert in essential semiconductors, announces two Electrostatic Discharge (ESD) protection devices optimised for use with retimers and redrivers on high-speed data lines. PESD2V8Y1BSF is designed to protect USB4 (Thunderbolt) interfaces while PESD4V0Y1BCSF is intended for use with both USB4 as well as HDMI 2.1.
These products use Nexperia’s proven TrEOS technology, which combines low clamping with low capacitance and high robustness. Retimers and redrivers are commonly used in the design of high-speed USB4 interfaces. However, these result in shorter board traces which have a lower parasitic inductance, an unintended consequence of which is a reduction in the overall system-level ESD robustness.
