The 2027-07-BLF is a 2-pole gas discharge tube designed for overvoltage and surge protection across telecommunications, industrial, commercial, consumer, and automotive electronics. It features an 8 mm diameter and 6 mm length with a DC sparkover voltage of 75 V (±20%) at 100 V/s and impulse sparkover ratings of 300 V at 100 V/µs and 500 V at 1000 V/µs. The device offers high surge current capability with ratings up to 25,000 A (8/20 µs) for single operation and maintains stable breakdown characteristics throughout its operational life. With insulation resistance exceeding 10^10 O at 50 V, glow voltage greater than 70 V at 10 mA, and operating temperature range of -55°C to +125°C, this RoHS-compliant component provides reliable protection in demanding environments. The tube is UL recognized and suitable for custom configurations, making it ideal for protecting sensitive circuits from transient overvoltages in network and communication systems.
