■ 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

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. 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 breakdown 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.

Notes:

• 2038-35 UL Recognized

, 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.

• Sparkover limits after life 30 ꢀ. IR >10 Ω.

• Operating characteristics per RUS PE-80 and Telcordia GR 1361 available on request.

• At delivery AQL 0.65 Level II, DIN ISO 2859.

Line to Line DC Sparkover tolerance typically less than +30 ꢀ at 100 V/s.

Network applied.

DC Sparkover may exceed 30 ꢀ but will continue to protect without venting.

*RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011.

Speciﬁcations are subject to change without notice.

Customers should verify actual device performance in their speciﬁc applications.
