DBT72475SU is a UL-approved normally closed high voltage reed relay designed for applications requiring very high isolation voltages. It features tungsten contacts with 7.5kV isolation across contacts, a 24V DC coil with 925O resistance, and can switch up to 5000V DC/AC peak with a maximum switching power of 50W. The relay offers PCB mount with stud fixing and 1/4" spade HV connections, operates within a temperature range of -20°C to +70°C, and provides 17kV contact-to-coil isolation. Common applications include cardiac defibrillators, test equipment, and high voltage power supplies where high reliability and isolation are critical.
