■ Stable breakdown throughout life  
■ RoHS compliant* versions available  
■ Balanced Mini-TRIGARD™  
(5 mm diameter, 7.5 mm length)  
■ Ideal for board level protection of  
broadband circuits  
■ Symmetrical breakdown voltage (L-L, L-G)  
■ Leadless, surface mount for economical  
assembly  
2038 Series Miniature Symmetrical 3-Electrode Surface Mount Gas Discharge Tube  
Bourns offers a symmetrical surface mount (SM) 3-electrode GDT surge protection device. The industry-leading quality and features of the  
®
TM  
Bourns miniature-TRIGARD series GDT continue in the 2038 symmetrical version. The 2038 series is ideal for board level protection of  
high bandwidth applications such as xDSL, cable broadband and high speed Ethernet, due to its symmetrical turn on characteristics as well as  
high energy-handling capability, long and stable life performance and low capacitance of less than 1 pF. The 2038 series breakdown  
voltages are nearly equal line to line as well as line to ground. Typical 3-electrode GDT line-line breakdown voltages are 1.8-2 times higher  
®
than the line to ground breakdown voltage. Bourns Gas Discharge Tubes (GDT) are designed to prevent damage from transient disturbances  
by acting as a “crowbar” in creating a virtual short-to-ground circuit during conduction. When an electrical surge exceeds the defined break-  
down voltage level of the GDT, the gas becomes ionized and rapid conduction takes place. When the surge passes and the system voltage  
returns to normal levels, the GDT returns to its high-impedance (off) state.

, file E153537, 2038-110 CSA Approved  
, file LR93265 (UL 1449).  
• The rated discharge current for Mini-TRIGARD™ GDTs is the total current equally divided between each line to ground.  
• Surface Mount (SM) parts may show a temporary increase in DCBD after the solder reflow 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.
