CG2 Gas Discharge Tubes (GDTs)

Littelfuse CG2 Gas Discharge Tubes (GDTs) provide a high degree of surge protection in a small size, making them ideal for board-level circuit protection. These GDTs function as switches to dissipate a minimum amount of energy and handle currents that surpass other types of transient voltage protection. The CG2 series features a 145V to 1000V DC sparkover range, which is ideal for protecting equipment with higher voltage limits and holdover voltages. The gas-filled, rugged ceramic metal construction is highly reliable and well-suited for adverse environments. Littelfuse CG2 GDTs are available in various forms, including surface mount, core, straight, and shaped leads. Applications include data lines, power supplies, communication lines and equipment, medical electronics, and instrumentation circuits.
