DBR71275TU is a UL-approved normally closed high voltage reed relay designed for applications requiring high isolation voltages. It features rhodium contacts with 7.5 kV isolation across contacts, a maximum switching voltage of 1000 V DC/AC peak, and a maximum switching power of 50 W. The relay operates with a 12 VDC coil (must operate voltage 9 V, coil resistance 240 O) and offers low contact resistance of 50 mO maximum (15 mO typical). With PCB mount and wire wrap HV connection terminals, an operating temperature range of -20°C to +70°C, and 17 kV contact-to-coil isolation, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
