Features n Through-hole or cassette mount n Low capacitance and insertion loss n High surge current rating n Fast response to transients n Compact mini size n RoHS compliant* version available 2039-xxx-XX Precision, Fast Responding, High Voltage Gas Discharge Tube Bourns now offers miniature through-hole 2-electrode GDT surge protectors with sparkover voltage up to 1100 V. At only 5 mm in diameter, the 2039 Series is ideal for board level protection of high bandwidth applications such as xDSL, cable broadband and high speed Ethernet. The 2039 Series features high energy-handling capability, long and stable life performance and low capacitance of less than 1 pF. Bourns GDTs are designed to prevent damage from transient disturbances within rated limits by acting as a crowbar to create a short-to-ground circuit during conduction. When an electrical surge exceeds the defined breakdown voltage level of the GDT , the device becomes ionized and rapid conduction takes place. When the surge passes and system voltage returns to normal levels, the GDT returns to its high-impedance (off) state. Characteristics Test Methods per ITU-T K.12, IEEE C62.31 and IEC 61643-311 GDT standards.
