Gas discharge tube SPI series

Gas Discharge Tube (GDT) is a single-gap or multi-gap switching overvoltage protection device. Under normal circumstances, the GDT is in a high-impedance state; when suffer a surge, the GDT will change from a highimpedance state to a low-impedance state, and release the surge energy to the ground, reducing the residual voltage of the circuit, thereby protecting the equipment circuit or protect the human body from the hazards of transient overvoltage. GDT is formed by hightemperature sealing of metal electrodes, metallized ceramics, inert gas or other mixed gases. Features ● Fast Response ● Stable Performance Over Surface Life ● High Current Rating ● Low Capacitance ● High Insulation Resistance ● RoHS & REACH Compliant Applications ● Class Ⅰ 、 Class Ⅱ and SPD ● N-PE Mode Protection In AC Power
