Bourns GDT35 3-Electrode Gas Discharge Tube Arrestors

Bourns GDT35 3-Electrode Gas Discharge Tube Arrestors significantly improve protection from voltage transients caused by lightning or accidental contact with AC power lines. With improvements driven by computer modeling simulations, the Model GDT35 Next-Generation series provides an enhanced level of voltage limiting during fast-rising events to reduce stress on downstream components. For these 3-electrode variants, Bourns’ unique coplanarity fit allows the component to toggle in either direction until a three-point contact is established. The low capacitance and low insertion loss make the GDT35 3-Electrode Gas Discharge Tube Arrestors an ideal solution for protecting industrial communications and high-speed information and communication technology (ICT) equipment.
