2036-xx-SM Precision Gas Discharge Tube Surge Protector
Bourns now offers a surface mount (SM) 3-electrode Gas Discharge Tube (GDT) surge protection device. The industry-leading quality
and features of the Bourns® miniature 2036 TRIGARD™ series GDT continues in this new SM version for “pick and place” manufactur-
ing techniques. The 2036 SM device is ideal for board level protection of high bandwidth applications such as xDSL, cable broadband
and high speed Ethernet, due to its high energy handling capability, long and stable life performance and low capacitance of less than
2 pF. Bourns subminiature family of GDTs measure only 5 mm in diameter and are the smallest high performance GDTs in the telecom
industry. Bourns® GDTs are designed to prevent damage from transient disturbances by acting as a “crowbar” in creating a short-to-
ground circuit during conduction. When a voltage transient surge exceeds the defined 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.

Notes:
UL Recognized component, UL File E153537.
The rated discharge current for Mini-TRIGARD™ GDTs is the total current equally divided between each line to ground.
Sparkover limits after life 25 ꢀ (-25 ꢀ,+30 ꢀ for Model 2036-07, 2036-09 and 2036-60), IR >108 Ω.
Operating characteristics per RUS PE-80 and Telcordia GR 1361 available on request.
Line to Line voltage is approximately 1.8 to 2 times the stated Line to Ground breakdown voltage.
1 Network applied.
2 DC Sparkover may exceed 25 ꢀ but will continue to protect without venting.
