ROHM Semiconductor Unveils Ultra-Low Capacitance ESD Diodes for 10 Gbps+ Interfaces

  • ROHM Semiconductor launched the RESDxVx series of ESD protection diodes on May 21, 2026, targeting high-speed interfaces exceeding 10 Gbps.
  • The new diodes achieve ultra-low terminal capacitance of 0.24 pF (bidirectional) and 0.48 pF (unidirectional), with dynamic resistance reduced to 0.28 Ω.
  • The RESDxVxBASAFH and RESDxVxUASAFH models are AEC-Q101 qualified for automotive applications, including ADAS and autonomous driving systems.
  • Products are now available through DigiKey, with additional distributors to be added.

ROHM's new ESD diodes address a critical challenge in high-speed data communication: minimizing signal degradation while ensuring robust IC protection. As automotive and industrial systems demand stricter ESD requirements, ROHM's innovation positions it to capture share in high-growth segments like AI servers, 5G/6G infrastructure, and autonomous driving. The AEC-Q101 qualification further strengthens its automotive credentials, a market where ESD protection is increasingly vital.
