DBT71205FU is a UL-approved normally closed high voltage reed relay from the DB(UL) series, 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 flying lead HV connection for PCB mounting. 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, contact resistance of 250mO max (100mO typical), and 17kV contact-to-coil isolation, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
