The 2035-42-SM-RPLF is a miniature 2-pole gas discharge tube (GDT) from the 2035 series designed for overvoltage and surge protection. It features a 5 mm diameter and 4 mm length with a DC sparkover voltage of 420 V (±15% @ 100 V/s) and impulse sparkover ratings of 675 V at 100 V/µs and 850 V at 1000 V/µs, providing reliable protection against transient surges. The device exhibits high surge current capability with impulse discharge ratings up to 10,000 A (8/20 µs) and maintains stable breakdown characteristics throughout its operational life. With an operating temperature range of -55°C to +85°C and UL recognition, this component is ideal for telecommunications, industrial electronics, commercial electronics, and aircraft/military applications requiring robust transient protection.
