SIDACtor Protection Thyristor protect telecommunications equipment suchas ADSL Modems,Router, , Telephone, CCTV 

Camera,Digital Video Record,Video Capture Card,Twisted-pair video transmitter,CATV Splitter.....Etc.


SIDACtor Protection Thyristor are used to enable equipment to meet various regulatory requirements including GR 1089, 

ITU K.20/21,IEC 61000-4-5, YD/T 1082,YD/T 993,YD/T 950,TIA-968-A ,TIA-968-B



• 100% Lead-Free(RoHs Compliant )

• Cannot be damaged by voltage

• Eliminate hysteresis and heat dissipation typically found with clamping devices

• Eliminate voltage overshoot caused by fast-rising transients

• Are non-degenerative

• Have low capacitance, making them ideal for high-speed transmission equipment
