The DG471S is a Discharge Tube (GDT/TSS) Surface-Mount Device (SMD) from Dongchen. This device is encapsulated in an ultra-small 3.2x1.6x1.6 mm size, is RoHS compliant, and can be used for high-voltage discharge or surge protection. The DG471S contains a gas-filled monolithic structure that can rapidly extinguish the arcs caused by voltage and current surges. It features low capacitance, wide operating voltage, suppressed parasitic parameters, and low on-resistance. The DG471S is recommended for use in applications such as power supplies, digital circuits, and storage devices.
