  • Proven technology

  • Sofics ESD technology has been included in 4500+ mass-produced IC designs, corresponding to millions of wafers and silicon proven on 50 different processes including 180nm, 130nm, 90nm, 65nm, 55nm, 40nm, 28nm CMOS as well as on FinFET technology. More than 15 companies relied on Sofics ESD for their IoT chip designs

  • Broad solution spectrum

  • Sofics has developed flexible ESD solutions that can be customized for every type of interface. The clamps are used in Analog IO's and can be used to protect digital IO's. The technology is easily customized to fit various requirements on ESD robustness, leakage, capacitance, voltage rating...

  • Beyond standard specifications

  • Sofics creates ESD clamps with low parasitic capacitance for wireless interfaces. Some IoT applications require much higher ESD robustness like 8kV HBM. Sofics ESD protection clamps have very low stand-by leakage and if needed can tolerate a higher voltage, beyond the standard GPIO limits.



Sofics can support your next IoT design

  • Wireless interfaces

  • Sofics IP was used in Bluetooth, NFC, indoor positioning and sensor networks.The wireless interfaces need low-leakage ESD protection for LNA inputs with high Q factor. They also need ESD clamps with low parasitic capacitance. Sofics clamps provide standard ESD robustness and do not require a resistance in the signal path.


  • Battery powered applications

  • Customers have integrated Sofics ESD in systems running for 10-years on 1 coin battery. The leakage of our ESD cells is 100x lower compared to conventional approach. Huge improvements can be made in stand-by, sleep, operational modes and during power-cycles. Sofics has solutions available for interfaces and rail clamps.

  • Beyond standard voltage levels

  • Our IP was used for sensor interfaces, battery connections and more. We have delivered solutions for high voltage tolerance (5V and higher) and also protected interfaces based on thin oxide transistors (1V and lower) thanks to a flexible but deterministic solution set


  • Harsh environments

  • IoT devices are used in new environments, hard-to-reach locations. Sofics IP was used for body-implanted semiconductors. Our ESD clamps are easily scaled to any ESD/EOS protection level. Also Industry 4.0 devices require higher ESD robustness.
