The two-electrode type gas discharge tubes that comply with the IEC and EN standards are available in dimensions of Φ5.5mm x 6mm, Φ8mm x 6mm, Φ8mm x 7.9mm, and Φ8mm x 8mm. Maximum operating temperature options include 105°C for the GD52R, GD82R, GD82R-U, and GC82R Series, and 125°C for the GRC2R Series to meet different circuit design requirements. These TÜV-certified GDT products provide 8/20μs surge current ratings from 1.5kA to 20kA, and their DC spark-over voltage ranges are listed below:

• GD52R Series: 90V–3600V
• GD82R Series: 90V–1000V
• GD82R-U Series: 90V–600V
• GC82R Series: 600V–3500V
• GRC2R Series: 600V–3300V

These gas discharge tubes are suitable for surge protection in power system, including energy storage system, uninterruptible power supply (UPS), charging station, and industrial power supply; communication equipment, such as xDSL, cable modem, and communication line; and consumer electronics, such as cable television equipment (CATV), TV, and set-top box.
