Sankosha’s surge arresters provide fast protection for personnel, equipment and circuitry from high transient
voltages and limit resulting dangerous currents. These hermetically sealed gas discharge tubes have precise
sparkover voltages and the ability to handle high current surges. We offer a wide variety of GDT’s and it is
important that arresters be selected in accordance with the requirements of the particular application.
Arresters for special applications are also available and we welcome your inquiries if the model you need
is not listed here.
Gas Tube Surge Arresters
Surface Mount Arresters
Two and three electrode Surface Mount Arresters in different sizes feature Sankosha’s industry leading quality and reliability. These models are ideal for economical assembly systems using pick and place technology.
Two Electrode Arresters
Three Electrode Arresters
While two electrode arresters have the advantage of being lower priced, the opening in the center electrode of the three electrode arrester allows the two gaps of the arrester to share a common gas chamber and sparkover occurs almost simultaneously in both sides of the arrester minimizing the current surge in the protected lines.
High Voltage Arresters
Our Y08SV Series arresters meet the rigorous requirements of both UL 1449 and UL 1414 making them ideal for power supply protection applications.
