Gas Discharge Tube Surge Protector

Gas Discharge Tube

The PROSEMI Gas Discharge Tube (GDT) is a high-performance surge protection device designed to protect sensitive electronic circuits from transient voltage spikes, such as those caused by lightning strikes, power line crossovers, or switching events. By utilizing a sealed gas-filled tube, the GDT offers reliable clamping to divert excess voltage away from critical components, ensuring the longevity and safety of your equipment.

Ideal for applications in telecommunications, power supplies, automotive systems, and industrial electronics, the PROSEMI Gas Discharge Tube provides robust protection with fast response times and high surge handling capacity. It is especially effective in high-voltage environments where other surge protection methods may fall short.

Durable, cost-effective, and with excellent performance in extreme conditions, the PROSEMI GDT is an essential solution for safeguarding circuits against damaging transients, helping maintain system reliability and minimizing downtime.
