DBT71205TU is a UL-approved normally closed high voltage reed relay designed for applications requiring high isolation voltages. It features tungsten contacts with 5kV isolation across contacts (DC or AC peak), a 5VDC coil with 38O resistance, and PCB mount with stud fixing and wire wrap HV connection. The relay offers a maximum switching voltage of 3500V DC/AC peak, maximum switching power of 50W, and maximum switching current of 2A. With an operating temperature range of -20°C to +70°C and contact-to-coil isolation of 17kV, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
