The 2057-47-BLF is a light-duty 2-electrode miniature gas discharge tube designed for surge protection and overvoltage suppression in telecommunications, industrial, and consumer electronics applications. This compact device features a 5.5 mm diameter and 6 mm length with a DC sparkover voltage of 470 V at 100 V/s, impulse sparkover ratings of less than 900 V at 100 V/µs and less than 1100 V at 1000 V/µs, and a DC holdover voltage of 150 V. The tube exhibits low capacitance (less than 1 pF at 1 MHz), low leakage current (greater than 1 GO insulation resistance), and can handle maximum impulse discharge currents of 10,000 A (8/20 µs) for single operations. With its RoHS compliance, UL recognition, and robust performance characteristics including glow voltage of approximately 70 V at 10 mA and arc voltage of approximately 10 V at 1 A, the 2057-47-BLF provides reliable protection against transient overvoltages in demanding industrial and telecommunications environments.
