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 perfor-
mance 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.
