DBR72475TU 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 24V DC coil with 925O resistance, and 17kV contact-to-coil isolation. The relay offers low contact resistance of 50mO maximum (15mO typical), maximum switching power of 50W, and switching voltage up to 1000V DC or AC peak. With an operating temperature range of -20°C to +70°C, operate time of 2.0ms, and release time of 3.0ms, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
