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”
manufacturing 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.
• No model number marking on tube; date code and voltage only: month year digits, xxxV (e.g. 0209 400V).
• 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.
