Two-Electrode Standard Spark Gaps

Two Electrode Spark Gaps

High Energy Devices’ BX Series, SB/SG Series and TG Two-Electrode Legacy Series are designed for a wide variety of applications requiring the efficient transfer of high voltage, high energy pulses. Typical applications include overvoltage protection of magnetrons, diodes, capacitors, and other components in high voltage circuits and as switching devices in pulse generating circuits. High Energy Devices’ miniature spark gaps have been designed for applications that have severe environment and high reliability requirements and where cost is a major consideration.

BX Series

BX Series

The BX Series of miniature two-electrode spark gaps (2.0-20.0kV) has been designed for applications that have severe environment and high reliability requirements. These gaps are made with high alumina (Al2O3)ceramic cylinders and metal electrodes that are hermetically sealed at high braze temperatures to withstand extreme levels of temperature and rugged environmental conditions. The small size of the BX gaps allows alternative mounting methods, including circuit board mounting, as well as external clamping of the ceramic envelope by using low dielectric materials.
