Notes:

• 2038-35 UL Recognized , ﬁ le E153537, 2038-110 CSA Approved , ﬁ le 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 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 ±25 %. IR >108 Ω (+30 %, -25 % for 2038-60,-80 and -110).

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

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

Bourns offers a symmetrical surface mount (SM) 3-electrode GDT surge protection device. The industry-leading quality and features of the

Bourns® miniature-TRIGARDTM 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 deﬁ ned 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.
