## **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 7 POURNS **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.
