The 2027-35-B 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 350 V (±15% @ 100 V/s) and impulse sparkover ratings of 600 V at 100 V/µs and 875 V at 1000 V/µs, providing reliable protection against transient surges. The device exhibits high surge current capability with ratings up to 25,000 A (8/20 µs) for minimum operation and maintains stable breakdown characteristics throughout its operational life. With an insulation resistance exceeding 10¹° O, glow voltage greater than 70 V at 10 mA, and operating temperature range of -55°C to +125°C, the 2027-35-B delivers consistent performance in demanding protection applications. The tube is UL recognized and available in RoHS-compliant versions, making it suitable for modern telecommunications networks, industrial control systems, and automotive protection circuits.
