DBR71275SU 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 offers low contact resistance of 50mO maximum (15mO typical), an insulation resistance of 10^10O minimum, and operates over a temperature range of -20°C to +70°C. With a 12V DC coil voltage, 240O coil resistance, and 2ms operate time, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
