Littelfuse, Inc. has recently introduced the smallest square gas discharge tube (GDT) in the market, measuring just 5.0 x 5.0 x 4.2 mm. This compact GDT offers a 5 kA surge capability and maintains an ultra-low off-state capacitance of ≤0.7 pF, making it ideal for high-bandwidth applications. The SH Series GDT is specifically designed to protect against fast-rising transients caused by lightning interference, ensuring reliable performance in demanding environments.
The low off-state capacitance remains stable regardless of the voltage across the GDT, which means it won’t interfere with signal integrity. This makes the SH Series highly compatible with high-speed communication systems such as G.fast, xDSL, and 10GbE. It’s also suitable for protecting Ethernet ports, satellite coaxial cables, cable TV equipment, and industrial automation interfaces like RS-485 and RS-232.
In addition, the SH Series GDT is well-suited for AC power line protection in renewable energy systems, including power inverters and variable frequency drives (VFDs). Its small size and square design make it easier to handle during automated SMT assembly, reducing manufacturing complexity and improving efficiency.
Stephen Li, Global Product Manager for Gas Discharge Tubes at Littelfuse, stated, “The SH Series GDT is an excellent choice because it not only meets today’s high surge requirements but also supports high-speed, wide-bandwidth applications. Its compact form factor and simple mounting make it a great option for wireless base stations, cable modems, and other high-density designs.â€
Key advantages of the SH Series include:
- High surge tolerance in a small package, perfect for high-density layouts.
- Ultra-low off-state capacitance (≤0.7 pF) that doesn’t vary with voltage, minimizing signal loss.
- Square body and terminal structure for improved pick-and-place performance on PCBs.
- Wide range of applications across telecom, industrial, consumer, and renewable energy markets.
The SH Series GDT is available in tape and reel packaging, with 900 units per reel. Samples can be obtained through authorized Littelfuse distributors worldwide. For more information or to locate a distributor, visit Littelfuse.com.
