The 2035-15-BLF is a miniature 2-pole gas discharge tube designed for overvoltage protection in telecommunications, industrial, commercial, consumer, and automotive electronics. This device features a 5 mm diameter and 4 mm length with a DC sparkover voltage of 150 V (±15%) at 100 V/s, and impulse sparkover voltages of 350 V at 100 V/µs and 550 V at 1000 V/µs. The tube exhibits high surge current capability, supporting impulse discharge currents up to 10,000 A (8/20 µs) for minimum 1 operation, with excellent stability and low capacitance of less than 1 pF. Operating across a temperature range of -55°C to +85°C with insulation resistance exceeding 10¹° O, the 2035-15-BLF provides reliable protection against transient overvoltages while maintaining stable breakdown characteristics throughout its operational life. RoHS compliant versions are available, and the device is UL recognized (UL File E153537), making it suitable for demanding protection applications requiring compact form factor and high reliability.
