Specifications are subject to change without notice.

The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.

Users should verify actual device performance in their specific applications.

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.

Test Methods per ITU-T K.12, IEEE C62.31 and IEC 61643-311 GDT standards.
