DBT72405TU is a UL-approved normally closed high voltage reed relay from the DB(UL) series, designed for applications requiring very high isolation voltages. It features tungsten contacts with 5kV isolation across contacts (DC or AC peak), a 24VDC coil with 925O resistance, and wire wrap (turret) HV connection terminals with stud fixing. 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.
