Surge Protection for LED Lighting Systems
SFI’s multilayer varistors from the CSPD Family, SHV Series and SHC Series, are widely used in AC/DC power conversion and LED lighting systems such as DOB (Driver on Board).SFI products not only address surge-related damage in LED lighting applications but also meet safety certifications such as IEC61000-4-5, UL, and TUV, offering stable and efficient overvoltage protection solutions for leading global LED lighting manufacturers.
The SHV Series provides overvoltage surge protection at the power port in LED lighting applications by connecting the product in parallel to ground.


The SHC Series provides secondary overvoltage surge protection at the power port in LED lighting applications by connecting the product in parallel to ground.
