The Mini-TRIGARD 2036-xx-SM series surface mount (SM) 3-electrode precision 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 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. Operating temperature range is from -55 to 125°C.
