The 2037-35-BLF is a miniature 2-pole gas discharge tube designed for overvoltage and surge protection in telecommunications, industrial, commercial, and consumer electronics applications. This device features a 5 mm diameter and 5 mm length with a DC sparkover voltage of 350 V (±15% @ 100 V/s) and impulse sparkover capabilities of 600 V at 100 V/µs and 750 V at 1000 V/µs, providing reliable protection against transient surges. The tube is UL recognized, RoHS compliant, and rated for high surge currents up to 10,000 A (8/20 µs), with stable breakdown characteristics throughout its operational life. It operates across a temperature range of -55°C to +85°C and maintains insulation resistance greater than 10¹° O, making it ideal for protecting sensitive electronic circuits in demanding environments including aircraft and military applications.
