Features
■ Leadless, surface mount for economical assembly ■ Low capacitance and insertion loss ■ High surge current rating ■ Fast response to transients ■ Compact “mini” size ■ RoHS compliant* version available Characteristics 2039-xxx-SM Precision, Fast Responding, High Voltage Gas Discharge Tube *RoHS Directive 2002/95/EC Jan 27, 2003 including Annex. Specifi cations are subject to change without notice. Customers should verify actual device performance in their specifi c applications. Test Methods per ITU-T (CCITT) K.12 and IEEE C62.31 Notes: Surface Mount (SM) parts may show a temporary increase in DCBD after the solder refl ow process. Most devices will recover within 24 hours time. It should be noted that there is no quality defect nor change in protection levels during the temporary change in DCBD. Sparkover limits after life +30/-25 %, IR >108 Ω. At delivery AQL 0.65 Level II, DIN ISO 2859. 1 Network applied. 2 DC Sparkover may exceed +30/-25 % but will continue to protect without venting. Characteristic Model No. 2039-80-SM 2039-110-SM DC Sparkover ± 20 % @ 100 V/s 800 V 1100 V Impulse Sparkover @ 1000V/μs 1250 V 1500 V Bourns now offers miniature Surface Mount (SM) 2-electrode GDT surge protectors with sparkover voltage up to 1100 V. Compatible with “pick and place” assembly systems and 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 by acting as a “crowbar” to create a short-to-ground circuit during conduction. When an electrical surge exceeds the defi ned breakdown voltage level of the GDT, the device becomes ionized and conduction takes place within a fraction of a microsecond. When the surge passes and system voltage returns to normal levels, the GDT returns to its high-impedance (off) state. *RoHS COMPLIANTVERSIONS AVAILABLE
