Nexperia introduces the electrostatic discharge (ESD) protection diode devices suitable for the USB4

Update time : 2022-06-18 16:21:15

Nexperia, an expert in the field of basic semiconductor devices, announced the launch of two optimized electrostatic discharge (ESD) protection diode devices, which are suitable for retimer and signal repeater in high-speed data lines. Pesd2v8y1bsf is designed to protect the USB4 (thunderbolt) interface, while pesd4v0y1bcsf can be applied to USB4 and HDMI 2.1. Both products use Nexperia's mature troos technology, which combines the advantages of low clamping, low capacitance and high robustness.

Retimer and signal repeater are commonly used to design high-speed USB4 interface. They require short circuit board routing changes to reduce parasitic inductance, but also unexpectedly reduce the overall system level ESD robustness. Pesd2v8y1bsf and pesd4v0y1bcsf have low vftlp peak clamp voltage, even lower than USB4 protection solution without obvious trigger voltage in standard I (V) TLP curve. This helps to compensate for the reduced inductance between the protection device and the retimer, thereby improving the overall system level ESD robustness. In order to meet the ESD budget loss recommendations, both devices can provide ultra-low insertion loss (-0.29 dB at 10 GHz) and return loss (-20.6 dB at 10 GHz). Unlike other solutions, the capacitance does not increase with the operating voltage and provides complete RF performance up to the rever se cut-off voltage.
Compared with other ESD protection diode devices, pesd2v8y1bsf and pesd4v0y1bcsf can be placed directly next to the connector of the protected device, thus providing greater design flexibility. This means that the AC coupling capacitance is also protected. In addition, it places most of the line inductors between ESD protection and protected devices to optimize the ESD performance of the system. Stefan Seider, senior product manager of Nexperia, said: "Nexperia helps design engineers meet the insertion loss and return loss requirements of high-speed USB4 data lines with a limited budget by providing devices that minimize the impact of ESD protection on the total budget. These two devices achieve an excellent balance between optimizing system level ESD robustness and RF performance."
