Bourns GDT28H 2-Electrode Gas Discharge Tubes (GDTs) are designed to protect devices from voltage transients caused by AC power line disturbances and lighting. These high-voltage GDTs feature high insulation resistance, high current rating, wide operating temperature range, and long service life. The GDT28H GDTs are available with a 1kV to 3.3kV DC sparkover voltage range and are RoHS compliant. Typical applications include power supplies, medical devices, air conditioning, and IEC 62368-1 equipment.
