2056-35-B2LF Description

Short technical summary and product information.

The Bourns 2056-35-B2LF is a light-duty 3-electrode gas discharge tube (GDT) designed for overvoltage protection. It features a DC sparkover voltage of 350V with ±20% tolerance, and can handle impulse discharge currents up to 5kA (8/20μs waveform, 10 operations). The device has low capacitance (<2pF) and high insulation resistance (>1GΩ), making it suitable for high-speed signal lines. It operates over a temperature range of -30°C to +85°C. The component is housed in an axial cylinder package with three radial leads for through-hole mounting. It is RoHS compliant and UL recognized.
