Surge Voltage Protectors. SVPs are gas discharge tubes, hermetically sealed, composed of two or three electrodes properly spaced by insulators and filled with a rare gas. SVPs mainly serve to provide a conductive path for unwanted, excessive transients, which prevents the transient energy and associated voltages from damaging sensitive equipment and components, and from harming personnel.High Surge Current Capacity at 20 kA Maximum
Electrical Characteristics Common to All Types: Transition Time — 0.1 μs typ. RINS: ≥ 10,000 megohm. Capacitance: 1 pF typ. at 1 MHz. Operating and Storage Temperature Range: –40°C to +90°C.
