DBR70575SU is a UL-approved normally closed high voltage reed relay designed for applications requiring very high isolation voltages. It features rhodium contacts with 7.5kV isolation across contacts, a maximum switching voltage of 1000V DC/AC peak, and a maximum switching current of 3A. The relay operates with a 5V DC coil, with a must operate voltage of 3.7V and coil resistance of 38O, and offers low contact resistance of 50mO maximum (15mO typical). With an operating temperature range of -20°C to +70°C 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.
