*R oH VE S CO AV R M AI SIO PL LA N IA BL S NT E Features ■ Balanced Mini-TRIGARD™ ■ High surge current rating, low insertion loss (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 ■ Stable breakdown throughout life ■ RoHS compliant* versions available 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-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. 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.

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 >108 Ω. • Operating characteristics per RUS PE-80 and Telcordia GR 1361 available on request. • At delivery AQL 0.65 Level II, DIN ISO 2859. • Bourns recommends reflowing surface mount devices per IPC/JEDEC J-STD-020 rev D. (1) Line to Line DC Sparkover tolerance typically less than +30 % at 100 V/s. (2) Impulse Sparkover voltage is defined as typical values of distribution. (3) Network applied. (4) DC Sparkover may exceed ±30 % but will continue to protect without venting. *RoHS Directive 2015/863, Mar 31, 2015 and Annex. Specifications are subject to change without notice.
