Littelfuse , Inc. today announced the introduction of the smallest (5.0 x 5.0 x 4.2 mm) square gas discharge tube ( GDT ) on the market today with 5 kA surge capability and ≤ 0.7 pF off-state capacitance. The SH Series GDT is designed to provide a high level of protection against fast rising transients caused by lightning interference. Its low-off-state capacitance meets the requirements of high-bandwidth applications, and its capacitance does not change with the voltage signal across the GDT . This series is specifically designed to protect electrical, multimedia, and communications equipment from damage caused by overvoltage transients.
SH Series GDT Product Picture
Typical applications for SH series gas discharge tubes include G.fast, xDSL, 10GbE and 10/100/1000Base-T Ethernet port protection for the telecom/datacom market; satellite coaxial cable for consumer markets, cable TV equipment and set-top boxes Protection; Industrial automation interface protection for industrial markets such as Ethernet, RS-485, RS-232, etc.; and AC power line protection in power inverters/Variable Converters (VFDs) for the renewable energy market.
Stephen Li, Global Product Manager for Gas Discharge Tubes at Littelfuse , said: "The SH Series GDT is the ideal solution because it not only meets today's high surge values, but also maintains compatibility with high speed, wide bandwidth applications. Protecting electrical and multimedia In addition to the overvoltage transients of the communication equipment, the SMT assembly pick-and-place process is simpler due to its square body and terminal structure."
SH series gas discharge tubes have the following main advantages:
The device's high surge tolerance in a very small package makes it ideal for high-surge, high-density layout applications such as wireless base station power and cable modems.
• Low off-state capacitance (≤0.7pF) minimizes insertion loss. At the same time, this value does not change with the signal voltage and does not affect the normal signal. This feature makes it compatible with high-speed, wide-bandwidth applications such as G.fast, xDSL devices, and cable modems.
Compared with the cylindrical GDT, the SH series square body and terminal structure are easy to pick and place, which is beneficial to simplify the PCB manufacturing process.
